Stinger (2005)

A lost submarine full of super-secret booty reappears, and the team of Marines and smarties sent to investigate finds themselves smarting in Stinger (2005), a deep-sea-scorpion horror of the really, really, really B sort. You'll be amazed at just how B a B-movie can be when you take a gander at this mammerjammer. Genetic-scientist-with-mighty-good-genes Michelle Meadows is the head of the expedition to the SS Newark, where it appears that the entire crew, save one, is resting in pieces. The survivor tells a hell of a tale about super scorpions--and Michelle decides that they've got to buck up and go deeper if they're going to get to the mutant heart of the matter. Farther and farther into the sub they go, on the tail of sheer terror, getting stung one-by-one by those venomous son-of-a-guns. Stunner Daniella Vesterlund is the standout in the pack--her rack pokes out like a pair of periscopes. However will this crew of tried-and-true types survive the dank corridors and tight spaces of the Newark? Daniella, point them in the right direction!
