Two models, Marlis and Peggy, are on a Caribbean Island for a photoshoot. One night, Peggy is found dead and her body seems to be eaten by rats.

The victim's sister, Terry, arrives on the island and helped by Fred Williams, a mystery novel writer she meets at the airport, starts to investigate. Meanwhile, Marlis and the photographer find other corpses in the jungle.

Todd Martin of Horror News Network had praised the film for its gore and acting of Nelson de la Rosa and Eva Grimaldi but criticized the film for its long and boring scenes where blood and gore were not the factors. John White of The Digital Fix gave the film 7 out of 10, criticizing its visual presentation but also mentioning that "Those who love bad monster movies will open their heart to Ratman."
