It is right before Christmas and Andrea is called in by an insurance company to investigate a death on board of an oil rig. Once aboard the rig, Andrea starts suspecting something more sinister may be going on.

A hurricane has hit the area and the crew is stuck on the rig with no help in sight. After a second accident Andrea is convinced there is a saboteur on board, but getting answers is turning out to be difficult as some secrets are uncovered.

There has been a murder on the rig, confirming the suspicions that someone on board has been causing the accidents. The rig has been damaged and disconnected from the outside world, increasing tensions between the crew members.

The rig has been damaged so severely that the crew are forced to turn the power off in order to secure it as the investigation goes on. The number of victims increase as the crew are working to re-establish contact with the outside world.

The remaining crew is split into two groups as everyone suspects each other of being the murderer. Tensions rise and as the crew buckles down, waiting for help to arrive, they realize they must start talking in order to solve the mystery.

A game of cat and mouse erupts among the people on the rig as the hurricane seems to be moving away from the area. Who is guilty and who will survive until rescue are able to reach the rig?
