A tsunami floods Malibu and unleashes a hunting pack of deep-water prehistoric goblin sharks, targeting a group of lifeguards trapped in their half-submerged station on stilts and a team of construction workers stranded in a flooded house.
It's pretty bad when you're calling a Goblin Shark prehistoric, all sharks are... And they aren't endangered nor have they "not been seen for millions of years", they're rare because they're deep sea dwelling sharks that don't show aggression because they don't interact with people. Completely ridiculous, stop trying to make the new "Jaws" it's just not going to happen.
