At a pterodactyl's nest several of the eggs hatches. A trio of hunters, scouting the Turkish/Armenian border are suddenly attacked by a pterodactyl. While defending themselves, they become outmatched and are all killed.
Michael (Cameron Daddo), and Kate (Amy Sloan), are leading a group of teenagers for camping and through a science expedition. The students are Gwen, Jason, Willis (Steve Braun), and Angie (Mircea Monroe). They stop at a Turkish forest and begin exploring, eventually discovering a dead pterodactyl and mounds of pterodactyl feces. While the others examine the spore, Angie wanders off and decides to go for a swim. When she jumps into the water, a pterodactyl appears and attacks her. She struggles to escape, and runs into Jason, who was searching for Angie. In the confusion, he moves to the lake to investigate. Upon reaching the lake, the pterodactyl drags him away. Angie tells the others that she was attacked by something that looked like a bird, but Michael dismisses the idea. Michael and Willis desperately go searching for Jason, but unnoticed by them, he has been killed.
That night, Captain Bergen (Coolio) and his squad sneak into the Russian camp and captures the terrorist Clarke, (Todd Kramer). Captain Bergen find Michael and his group camping, so they decide to follow them.
The next morning, while preparing to leave, Michael's jeep is ambushed by a group of Russian terrorists.

Michael questions their precence; Bergen says that he and his squad members have been assigned to capture a Russian terrorist by hand. While the group continue on foot, Angie shows her feelings to Willis, for his bravery.
A second wave of pterodactyls suddenly appear. During the attack, Angie is wounded and succumbs to her injury. Several soldiers are also killed, and Kate is snatched in the process. After the attack, Captain Bergen and the group continue, to find a shelter. Flocks of pterodactyles start raiding the shelter, bringing it down to pieces. The group, arms and defends themselves from the invaders. With the group gaining the upper hand, the remaining invading pterodactyls retreats. Willis and one of Bergen's remaining soldiers Zelasny are injured. They are told to remain at the shelter, while the rest journey to the nest to rescue Kate.
Later, Zelasny (Jessica Ferrarone), dies from her wounds and Willis is killed by invading pterodactyls. Meanwhile, in the nest, Kate grabs a soldier's walkie-talkie and contacts Bergen. She escapes the nest and runs over the group once again. When the rescue line is set up for Kate to cross, Serling (George Calil), travers and grabs Kate to swing to Michael.
