This early bit of "B"-movie fluff from Roger Corman and company is a hastily slapped-together melange of crime thriller and monster flick, laced with enough ham-fisted satire to make the entire mess enjoyable. The plot centers on a two-bit crook (Antony Carbone) who offers to transport a band of exiles from a war-torn Caribbean country -- along with a coffer of cash, which he intends to keep for himself. After killing his charges and dumping their bodies in the ocean, he blames their deaths on a sea monster told of in local legends -- a beast which eventually shows up for real. The lush tropical settings of this weekend wonder are the same lush tropical settings seen in Corman's Last Woman on Earth, which employed most of the same players as well. Corman protégé Monte Hellman served here as second unit director before embarking on his own low-budget film career.
