When they were young men, Kim and his best friend, Garland Rain, travelled the world. They worked as dive guides, living free and easy by the sea. Garland is still out there, but Kim's life is different now. He's married and a father of three. Still longing for the freedom of the water, Kim agrees to help Garland run a one-time trip to the spectacular Brothers Islands in the Red Sea. What neither man expects is just how badly wrong it will go. Drugs and violence collide, and not everyone returns safely. Back on dry land, Kim finds that the decisions you make in the moment can come back to haunt you, even follow you home.
