The series is a children's game show set 100 years in the future in the year 2110. The world has been taken over by the evil Roboidz who were built to aid humans. They have destroyed everything and Caleb is the only person left. He is part human and part machine and does not remember anything about before the robots took over, due to memory loss. Earth's last hope is to destroy and rid the world of the Roboidz. Children are brought into Future Gate where they undertake challenges in groups of four until only one is left under the watchful eye of Caleb. When four of the best recruits are assembled they tackle Future Gate in the final of the show. Each episode's opening titles are headed with a safety warning:
"Mission 2110 is set in the future and the adventures you are about to see are controlled by trained professionals. Please do not try any of the missions performed in the show at home."
At the end of every episode, apart from the last episode of each series, Neuros is heard over the credits saying that Caleb won't succeed.
Caleb is the last human left and in order to save the planet and mankind he enlists the help of brave recruits from 100 years ago (2010). Caleb brings the recruits to Future Gate where they meet the Roboidz and other similar creatures. They then undertake challenges while earning bio rods that fuel the Roboidz. The recruits arrive in groups of four, two girls and two boys, and they are tested over three episodes. Four groups of recruits are tested until only the four elite recruits remain. During the series more of the background of Caleb and the Roboidz is revealed through Cybele. Caleb is keen to learn of his past, but Cybele is reluctant to tell him. Caleb also gradually becomes used to being around children and starts to show that he is emotionally attached to them. Cybele regularly has to remind Caleb of his task and duty and to not let emotions get in the way.Caleb Lansing-Gant (Stuart Goldsmith) - Part human, part machine. He can remember nothing of his past before the Roboidz took over. He wants to know about his past, and that of the Roboidz. Playing the game on the CBBC website reveals that he is the reanimated son of Laura Gant and Simion Lansing. He caught an unknown disease at the age of 17 and fell very ill. After his parents gave up on any hope of finding a cure, they cryogenically froze him. After waking up, Caleb has no recollection of his previous life.
Cybele (Lindsay Duncan) - Knows Caleb and about his past. Caleb's only ally apart from recruits. She was thought to be Neuros after hearing, at the end of series 2 episode 1, "My Unfortunate Hero". This theory however is debunked at the beginning of series 2 episode 3, when before signing off, she reveals she is Caleb's mother, but it is possible Neuros is his mother as she told Caleb that Cybele is the conscience and that Neuros is the brain of Laura Gant.
Neuros (Lindsay Duncan) - The main computer system controlling all the Roboidz (really a brain in a bio-rod-like container, hence her name), she was powered down in N-LAB, but was powered back up after the end of that series. She is seen in the credits at the end of each episode (except for the last episodes of series 1and 2 where she physically appeared as part of the final challenge "Neuros Web")
Roboidz (voiced by Gareth Jones, Rich Garraghty & Noel Byrne) - The Roboidz are robots that were (as revealed in series 2, episode 4) originally created by Laura Gant (Cybele) to aid humanity. Now, due to a revolt on Gamma FI4, they have destroyed the planet and got rid of any remaining humans. They were powered down in every place at the end of series 1, but reactivated by their leader, Arkon. They come in different classes, each a different colour and wielding different weaponry:
Worker - Drone Class - They are yellow with black stripes and do all the menial jobs around Future Gate, armed with the strength of ten men and pincer claws which can destroy anything, particularly Caleb's recruits. Luckily for the recruits, they are the least intelligent of the Roboidz.
Wardroid - Battle Class - They are red in colour and are the police force of Future Gate, armed with military training, a vector-beam rifle and boxing glove-like rip claws. Despite being the most dangerous of the Roboidz as Caleb describes them, they are pretty stupid.
Guard - Commander Class - They are silver in colour and although they have no visual ability, they instead have the latest radar tech. They are also the most intelligent of the Roboidz and armed with multi-digit claws which are more powerful then steel and can be fatal to a recruit
Arkon (Peter Dickson) - Led all the Roboidz to earth after the Gamma FI4 revolt and seemingly died at the end of series 1, but was shown to be alive as he powered up all the Roboidz again (including himself and Neuros). Unlike the other Roboidz, he had blue eye lights, a blue colour scheme and the ability of speech.
Shades (voiced by Gareth Jones, Rich Garraghty & Noel Byrne) - They used to be people before the Roboidz converted them into foul-smelling inhuman shades. They too were powered down everywhere.
Recruits - Children who are brought onto Future Gate to battle the Roboidz. After each episode they are either transported home or vaporised somewhere - Caleb and the remaining recruits don't know where.
The episodes all have the same format. The same group of recruits are present for three episodes, during which they are gradually reduced to one. The same challenges are undertaken by all 16 recruits.Day 1 - The four recruits are introduced. They then undertake the challenge Shade Alley. Next they face Live Wire. Their third challenge is the Frozen Vault. The final challenge of day one is Overload which is the only challenge undertaken as pairs on day one.
Day 2 - The four recruits undertake harder challenges as they try to progress. In the last challenge of the day, The Vaporiser, one of the recruits is vaporised and therefore removed. The remaining three recruits continue to the next day.
Day 3 - The remaining three recruits now undertake even tougher challenges. Only one recruit can continue to the next stage of the quest. Numbers of bio rods are also re-set from the previous days totals to give everyone an equal chance of progressing to the next stage of the contest.
When the elite recruits have been found they undertake harder and different challenges in one day.

At the end of episode 13, Caleb faced Arkon and Caleb pushed him off the edge of the Future Gate ship he was standing on and he plummeted into the water. However at the end of the credits, where we saw Neuros powered down, we saw a roboid's hand which linked to series 2.

In all episodes in Series 1 and Series 2 to date, Caleb has always drawn girls before the Vaporiser.
In Series 2 episode 5, for the first time, Kieran, Callum and Lois were all in the path of the roboidz while facing the Vaporiser, but with Lois having only three bio-rods compared with Kieran's 5 bio-rods and Callum's 6 Bio-rods she was vaporised.
At the end of Series 2 episode 13, Caleb faces Neuros for the first time. Neuros taunts Caleb and tells him he's a hybrid (human-machine). However Caleb retaliates by saying that's he's not listening thanks to his mother Cybele. Neuros however informs him that she's the actual mother of Caleb since she's the brain of Laura Gant and Cybele is her consciousness. Then Caleb, refusing to believe this, takes Neuros off her stand and angrily smashes her on the floor of the powered-down Vaporiser, presumably killing her once and for all. After the credits we then see the vaporiser powering up again which could mean that Neuros is still alive (as presumably is Cybele) and thus link to series 3.
Series 3 was rumoured to be in production, but according to Stuart Goldsmith, "no more missions are planned at present".
In August 2010, the "Mission 2110" camera crew (series 1&2) Pete Kelly, Allen McLaughlin, Hugh Creaney, plus Adrian Croome (Jib) and Adam Rogers (mini-cams), were nominated for a Royal Television Society award for multi-camera work. The winners were announced at a ceremony in London on November 24, 2010, but they had lost.
