A tsunami hits the coast of Australia, trapping a group of (mostly pretty) people inside a flooded grocery store. Oh and there's a shark trapped in there with them. Okay, so just when you thought they couldn't come up with any new twists in the killer shark subgenre of horror, they go and come up with the brilliant idea of a shark in a grocery store. It's all pretty stupid but also kind of fun. It's a watchable popcorn flick. The Aussie cast is nice, including former H2O co-stars Phoebe Tonkin and Cariba Heine. They aren't mermaids here but that would have been cool. There's really nothing about this movie that stays with you after seeing it but, while you're watching, you'll probably enjoy it well enough.
