Plot Synopsis

When an off shore earthquake sends a Tsunami wave rolling towards the California coast, it simultaneously releases five monster-size prehistoric sharks from a lost sea deep beneath the earth's crust. As the hungry sharks chase down swimmers, sunbathers and parasailors alike, it falls on Malibu lifeguard Doug Crenshaw and his team to protect the public from the ravenous monster fish while preparing for the destructive power of the tidal wave. But once the wave strikes, the killer sharks wind up in places you'd least expect to find them. A group of lifeguards and a crew of construction workers are stranded in the high water and have to fight the sharks to get to dry land.
