Triangle (2009)

Jess and her autistic son Tommy are joining friends on a yacht, but their pleasure cruise is cut short when they end up caught in a storm. And the cruise ship they stumble across may appear abandoned at first, but strange events slowly begin to convince them that there's more going on than meets the eye. The question of what would cause people to abandon the cruise ship in the first place is enough to make Jess afraid, but the group of friends is also being stalked by some sort of invisible creature. But with a storm raging outside, they're forced to stand their ground.
