Since its fight with the Pteracuda, the Sharktopus is still at large and is lurking in the waters of the Dominican Republic. An alcoholic boat captain named Ray (Casper Van Dien) and his sidekick Pablo (Jorge Eduardo de los Santos) are enlisted by a voodoo priest named Tiny (Tony Almont) to obtain the heart of the Sharktopus. Meanwhile, Dr. Reinhart (Catherine Oxenberg), a mad scientist who studied with the late Nathan Sands and the late Rico Symes from the previous two Sharktopus movies, mixes the genes of a killer whale and a wolf (resembling the extinct Pakicetus, an ancestor of modern whales). The resulting treatment transforms Felix Rosa (Mario Artura Hernandez) into the Whalewolf, which causes havoc and results in it fighting with the Sharktopus, then he dies.
Felix Vasquez Jr. of Cinema Crazed would not call the film "a masterpiece, but it's guilty fun".[2] Dylan Grable of Medium.com stated that the film had comedic value, being "so crazy that it culminates in a stupor of stupidity and entertainment".[3]
