Sometimes the simplest ideas are the best ones. Like, oh, I dunno... a live shark in a supermarket? Yes, from the great continent of Australia, the place that gave us Mad Max and Crocodile Dundee, comes Bait 3D. It's about a group of folks trapped in a grocery store after a tsunami hits their town. And their life-or-death struggle against a great white shark that's trapped with them. Check out the film's red band trailer below.
