Sleazy pet store owner Lou Gutchel (Sydney Lassick) has been dog-snatching puppies for the illegal research experiments of unscrupulous pharmaceutical executive Slade (Dean Jagger).
A baby alligator flushed into the Chicago sewer system has grown to an enormous size by feeding on the carcasses of pets injected with a growth hormone.
Detective David Madison (Robert Forster) meets herpetologist Marisa Kendall (Robin Riker) while investigating both the pet disappearances and a spate of dismemberment murders in the sewers.
Nobody believes him after he barely escapes from a massive, 36-foot killer gator loose in the streets beneath Chicago. This creature is gigantic, voracious and insatiable – and it will eat anything (as you might imagine, considering where it lives).
At the outset, the film smacks of just another absurd horror outing, but director Lewis Teague quickly lays on the style and excitement.
There are polished special effects, a serviceable script and capable performances from Forster and Riker. This reptile is not a match for the shark in Jaws, but it does have plenty of bite (sorry!).
