Filmed in Fiji and Australia, the coral visuals are gorgeous. But ironically, the plot’s “dangerous reef” feels safer than the script. The underwater tension works; the on-land betrayal scenes do not.

The first film was about greed vs. doing the right thing with stolen cocaine money. This one turns into an eco-thriller: the “treasure” is rusty mustard gas bombs. The villains want to sell them; the heroes want to destroy them. It’s oddly prescient about forgotten underwater munitions—a real environmental threat often ignored in action films.

Unlike the original’s A-list cast, this stars Chris Carmack and Laura Vandervoort. They’re B-level, but they actually perform many of their own underwater scenes. The result is clunky dialogue but surprisingly authentic diving sequences—less Hollywood gloss, more “two friends holding their breath for real.”

Two professional divers-for-hire (a new couple, not Paul Walker/Jessica Alba) are tasked with finding a legendary treasure on a dangerous reef. They soon discover that their clients are ruthless mercenaries hunting for a lost WWII cargo of deadly chemical weapons.
