"Monster Shark" opens with a Coast Guard helicopter scouring the waters off the Florida coast. Locating the wreckage of a boat, the chopper dispatches divers who recover the body of a man. As the body is hauled out of the water it becomes apparent that this was no normal boating accident - the poor fellow's legs have been gnawed off! Meanwhile, oceanic researcher Dr. Bob Hogan (Lawrence Morgant) is on a research vessel nearby making a survey of the area. He is shocked when he detects the presence of a massive and unknown underwater creature on his sonar.
Determined to discover what exactly the strange animal is, Hogan and his assistant Dr. Stella Dickens (Valentine Monnier) turn to local electronics whiz Peter (Michael Sopkiw) to help them build specialized equipment for the search. However, Peter's efforts are temporarily halted when he is roughed up in his workshop by a group of thugs who smash what he had been working on and then flee.
Stella and Hogan initially believe that the sea beast - which has continued to take victims at regular intervals - may be a prehistoric shark. However, as more is learned about the biology of the creature, and as other strange things begin to happen in this small town - including murder - the trail starts to point not towards the seas of ancient times but towards the West Ocean Institute, a nearby genetics laboratory run by the somewhat sinister Dr. West (William Berger) and his assistant Dr. Davis (Paul Branco), who may know more than they are telling!
