As shark-infested storms grow stronger and more complex, the world braces for the inevitable - a global sharknado. This year, the mission gets personal for chainsaw-wielding leader Fin Shepard and his bionic wife, April, when their young son gets trapped in a sharknado and is transported all over the world.

When an unprecedented amount of sinkholes erupt all over Florida, a new nest of fire spitting LAVALANTULAS is awakened... wreaking their fiery havoc all over the sunshine state. Adding to the mayhem, the arachnids have hit the beach where Colton West's (Steve Guttenberg) step-daughter, Raya (Michele Weaver), is taking a break from school. Now an A-list movie star, Colton walks off the set of his latest hundred million dollar blockbuster to save her. Armed with specialized weapons, Colton, his personal assistant, Kyle (James Bellinger), and his best friend, Marty (Michael Winslow), race to save the residents of Florida from these hellish prehistoric beasts and taking on the biggest, baddest one of them all!
