While away in Afghanistan, a decorated Marine, David Cooper, leaves the protection and care of his new wife, Vivian, to his best friend John. After Coop's tour ends, he has trouble integrating back into his old life. John, who is an orthopedic surgeon, has recently bought a yacht called Bella. He recommends that the three of them take a relaxing vacation on it.
Not long after the sea voyage begins, the two men experience tension between them because of John's familiarity and protectiveness toward Vivian and Coop's post traumatic stress disorder. When the ship malfunctions and leaves them stranded, Coop volunteers to go find help.
The nightmare that unfolds isn't what Coop had expected, but as a former marine he's more than prepared to deal with every threat.
