Beirut, Lebanon 2017. As the country trembles a man decides to attempt to break the world record of depth in deep diving.

High in the remote Welsh mountains, five builders are bought together to renovate a sprawling old farmhouse. Housed in mouldy portacabins, tensions soon simmer between the men and the self-entitled aristocratic homeowner, as well as amongst the rag tag group of men themselves. World-weary old timer Dave and kindly Foreman Bob try to keep the peace. But his nephew Steve falls under the malign influence of bigot Jim, the pair taking a dislike to Viktor, a Ukranian labourer. As the weather closes in and payments are late, tempers fray. Blood is spilled. As the blue-collar men are confronted with an increasingly dark spiral of moral choices, Jim makes an astonishing proposition.

Two policemen, one an old-timer, the other his volatile younger partner, find themselves suspended when a video of their strong-arm tactics becomes the media’s cause du jour. Low on cash and with no other options, these two embittered soldiers descend into the criminal underworld to gain their just due, but instead find far more than they wanted awaiting them in the shadows.

Paleontologist Robert Trenton (Dean Cain) is called to Northeastern Antarctica near the Indian Ocean to help the FBI build an underground maximum-security military base and prison for the world’s most dangerous criminals and terrorists. The prison is dubbed “New Alcatraz” by the staff. While building the prison, the staff accidentally awaken and unleash a prehistoric Boa Constrictor from its 200 year hibernation. The snake escapes unnoticed until the staff notice a massive hole chewed in the five-foot thick concrete walls. Soon, the staff, and prisoners begin disappearing as they are brutally hunted and eaten by the snake. The FBI agents, Trenton and the rest of the prisoners try to escape, but are hampered as they don’t have many weapons. They begin to give up hope as most of the survivors die. However, Trenton manages to blow up the snake underground before escaping to the surface with the only other survivor being his wife.
