Sharkman

Paul King (Anton Argirov) dies of kidney cancer. Five years later, his father Preston King (Jeffrey Combs), a scientist, invites the doctors that could not save his son to his uncharted island in the western Pacific. Paul's widowed wife Amelia Lockhart (Hunter Tylo), who believes Paul died five years ago from cancer, and Amelia's new boyfriend Tom Reed (William Forsythe (actor)), also travel to the island. There, King reveals that Paul never died and was saved from death by being injected with hammerhead shark DNA to modify his stem cells. This turned Paul into a half-man/half-shark creature. King releases the water from the tank where he was keeping Paul, in hopes that he will eat the doctors as revenge for them firing him from his job five years previously. As Paul, now known as Hammerhead, chases after them, they escape along with Hammerhead.
