Blue Lagoon: The Awakening (2012)

Emma and Dean are two high-school students on a class trip to Trinidad to build a school for less fortunate children and to explore the island. The two have little in common. During a boat party, Emma falls overboard when the party is interrupted by a police raid and Dean jumps in the water to save her. Dean then severs the rope attaching the dinghy to the party boat as he doesn’t want to get in any more trouble than he already has. The pair drifts to a deserted island, avoiding dangerous rocks by using the one paddle in the dinghy. Back home, their parents have been alerted that the pair was last seen on the party boat, and the parents desperately search for them. Wondering if they will ever be rescued, Emma and Dean must rely on each other to survive.
