The story lines are centered around a fictional hotel in Oslo, its employees, and the Anker-Hansen family. From the start, CEO and widower Georg Anker-Hansen (Toralv Maurstad) was one of the most central figures in the series and his romance with the escort girl Ninni Krogstad (Henriette Lien) was the main story. After a year Georg died of incurable cancer in the pancreas, and Ninni inherited the entire concern, which led to major conflicts with Georg's dominating mother, Astrid (Sossen Krogh), and especially Georg's children, Juni (Anette Hoff), Jens August (Kim Kolstad), and Julie (Elin Sogn).
So far, the series was mostly inspired by the history of Janni Spies, where Janni Brodersen married the much older Danish tourism king Simon Spies, and inherited millions when he died. It gave the idea to the hotel-owner Georg Anker-Hansen and the escort girl Ninni Krogstad.
The story of Georg's daughter Juni was also pretty much in the center in the beginning, due to her alcoholism. It received great attention in Norwegian media. The show received even more attention when the half siblings Jens-August (Kim Kolstad) and Charlotte Iversen (Kristin Frogner) began a relationship without knowing that they were siblings.
Later, the series focused on topics such as racism, kidnapping, rape, abortion, trafficking, drugs, pyromania, homosexuality, murder and other controversial topics.
In autumn 2004, episode No. 1000 of the series was sent, where Toralv Maurstad made a guest appearance as Georg in some of the characters dreams.
In January 2006, the series changed its genre and appeared as a more innovative and modern soap with more action, humor, sex, violence and drama. The show received massive media publicity because of its controversial content and early prime time. After the sudden change in the series, the viewing rates decreased, and this resulted as of January 2007, that the show gradually returned to its old style.
Years later it was discovered that Georg's deceased wife, Ingeborg Anker-Hansen, had an affair with Harald Hilldring, which resulted in the birth of Julie Anker-Hansen, who was the artist and the outsider of the family. She learned about this through her mother's diaries. Julie also claimed Georg responsible for her mother's illness, and among her siblings, she's the one who have the smallest issue about being against her family's opinions.
Jens August came out of prison at the start of the series, because he killed a young man driving under influence of alcohol. He also had a past with his father's new girlfriend, Ninni, and the relationship between Jens August and Ninni was always tense.
In the summer-cliffhanger of 2007, Jens August returned to the series, after being deserted on an island for two years. The plane was sabotaged by one an assassin sent by Scott Wallace, brother of Rolv Espevoll. Rolf, who was introduced to the Anker-Hansens in 1998. He had a brief affair with Juni during his 4 years working at the hotel. In 2002, he was set up for a murder, and later found guilty and sent to prison. He was released in 2006, where he in a short time with his brother Scott kicked out the Anker-Hansens of the hotel and their own concern. Throughout the few months they were in charge, Scott and Rolf developed a tense and hatred relationship. After some tense weeks, Scott wanted to get rid of Rolf, and planted a bag of cocaine in his hotel-room. Since Rolf recently was released from jail, this was a crucial move from Scott. After an anonymous call by him to the police, Rolf was arrested and was most likely to be convicted for drug-dealing. Rolf figured out that Scott was behind it all. And at the day of his trail, he ran off from the court. He visited Juni at Ankerseteren, gagged her, stole a rifle and ran down to the hotel, where he started shooting in the lobby. He killed 20 people including 2 people who held weapons too. Daphne wanted revenge from her ex for leaving her. When she pointed the gun at him, Rolf waited behind and shot her. The other one wielding a weapon was Julian, who was threatening his girlfriend, Benedicte, who've he had molested recently. Rolf ran into Julian and Benedicte when Julian was about to shot her. In a cheeky manner, Rolf pointed the rifle on Julian asking him to apologize to Benedicte for treating her bad. Nevertheless, Rolf shot Julian, who died instantly. Ironically then, Rolf saved 2 people from getting killed. He then went up to the office, where he pushed Scott out on the roof and talked straight out about everything he hated about him. Scott was already shot in his arm, and was not able to defend himself. Rolf ended up killing himself in the end.
In November 2007, June Anker-Hansen and Jens August Anker-Hansen was about to sell Virtual Window, a project developed by businesswoman, Nadia Selam-Tefari, who worked at Cæsar. Junis boyfriend at the moment, Magnus Falsen presented the Virtual Window to his lodge, Vox Populi, which seemed positive to the project.

Cathrine admitted when Tom Ivar was comatose, that she hoped he would die. Cathrine felt that she always was his second daughter after Cecilie, who he admired and loved openly.
In April 2009, Victoria Lunde, Junis daughter, came back to the series after many years in Belgium. She had turned into an alcoholic, which she probably inherited from his mother. Initially, Victoria held this hidden, but after several incidents throughout the fall of 2009, Juni figured out that her daughter needed help.
In the spring of 2009, Cathrine broke off from the Anker-Hansen Group, and started her own hotel chain, the Black Diamond. Jens August joined her after having a serious conflict with his family. Nevertheless, he returns to his family later.

When he left, Victoria joined him to go to rehab back in Brussels, Belgium.

In February 2010, Astrid's centenary was celebrated in 2000th episode of the show. At the end of this episode, Astrid got a stroke, and it turned out that she had cerebral hemorrhage. She survives, but loses her voice capability. However, Astrid died a month later.
This spring, Juni found out that Ingeborg is not her mother, as she thought over the years. Her real mother was her former nanny, Dagny Dallimore (who came into the series in late 2009). Before Juni was born, her family thought Ingeborg was not able to have a child. Therefore, Dagny said yes to carry Georg's baby. Astrid, Ingeborg and Georg set it up to make Juni think she was Ingeborg's daughter. Dagny was allowed to continue meeting her daughter as her nanny. But when Astrid and Ingeborg thought Juni and Dagny was to close, they blackmailed Dagny into leave the country. She moved to Australia, where she married a priest and got another daughter, Rose. Dagny told Juni about this. She also told Juni that Rose had a rough patch in her life, and that she had broke off all her contact to Dagny. Juni decided to go to Australia and find after her. Meanwhile, Junis daughter, Victoria, had completed her treatment in Brussels, returned to Oslo in April 2010.
This spring, Cathrine's hotel chain, Black Diamond, hit bankruptcy as a result when the chain's investor, Elliot Hiltun, was arrested for economic crimes, and thus get all their financial assets frozen.
