A cast of characters, strikingly similar to the cast of Jersey Shore, try to survive an epidemic of sharks attacking Miami Beach.

A baby dinoshark evolves into a ferocious predatory adult, terrorising tourists and locals offshore from Puerto Vallarta, Mexico.

Due to changes in ocean currents, shark activity appeared near a certain diving area, but the traces are unknown. The hungry shark is ready to move, waiting for an opportunity to start a merciless killing. Doctor Shen Xin was invited.
