Open Water 2: Adrift

A group of friends, Amy (Susan May Pratt), James (Richard Speight, Jr.), Zach (Niklaus Lange), Lauren (Ali Hillis), Dan (Eric Dane), and Dan's new girlfriend, Michelle (Cameron Richardson), go for a weekend cruise on Dan's new yacht. Amy is aquaphobic after a childhood traumatic event – as a young child, her father drowned while they were swimming together. The group realizes that nobody has lowered the ladder, leaving them unable to re-board the ship. They are left to tread water disconsolately. The group resorts to removing and using their bathing suits to make a rope. Meanwhile, James goes underwater, and messes with the prop, in an attempt to remove it and use it, but he drops the knife. He swims down after it and manages to catch it, then panicking under water, tries to swim for the surface. As he swims back up he crashes into the bottom of the boat, and is knocked unconscious. The group are now mostly naked and have only a partial swimsuit rope. Michelle screams and tries to retrieve Zach's phone from the ocean, but it is lost. They hear a phone ringing from Zach's clothes hanging slightly off the deck of the boat; however, the clothes fall into the water as Dan reaches for them. The phone goes dead, and Zach angrily throws the phone into the ocean.
