Bait 3d takes place in a sleepy coastal resort community, where shoppers at an underground supermarket find themselves terrorized by a crazed bandit when the unimaginable occurs... A monstrous freak tsunami swallows the town.
Now trapped inside a flooded supermarket with an armed maniac and rushing water threatening to entomb them all in a watery grave, tensions mount, tempers snap, and the imprisoned band of survivors discover the threat from without has ignited an even more immediate threat from within. Their own desire to survive whatever the cost.
However as hostilities reach breaking point the survivors discover they are not alone. The tsunami has brought some unwanted visitors from the depths, and as the waters rise they must overcome not only the threat of drowning and the human menace within their midst, but a threat more deadly than both and far more bloodthirsty... packs of hungry sharks.
