What do you do when you find a mutant cat living inside of a regular cat? First, you should hope the mutant cat isn't hiding an even smaller mutant cat inside of it. Next, you probably SHOULDN'T isolate yourselves on a yacht with a sociopathic Wall Street criminal. Fortunately for us, that's exactly what happens in this movie! Five partygoers on spring break find themselves stranded in the middle of the ocean with rich scumbags, Alex Cord and George Kennedy, as a poisonous and morally ambiguous cat wreaks havoc on them while cackling from the shadows. Will the hapless humans survive or will the cat dish out it's own kind of Final Justice™? Put in your false teeth, break out the champagne & corn flakes, and shout out a hearty 'FOOP', because we're chartering the 'Slam Dunk' to climb aboard Greydon Clark's Uninvited!
