Into the Blue (2005)

Divers Sam (Jessica Alba) and Jared (Paul Walker) love life in the Bahamas. But when friends Bryce (Scott Caan) and Amanda (Ashley Scott) visit, the couple take them on a treasure-hunting trip, where they discover more than they bargained for: a downed airplane full of cocaine alongside a famous shipwreck. Unknown to Sam and Jared, Bryce makes a fatal mistake and decides to sell the cocaine -- which angers a group of drug dealers, who are now in hot pursuit of the divers.
