During the trip to the family, the group of Fin stops on the way to save people, because they are attacked by sharks due to floods.

Having found their family, Alex Matt Fin's son joins them and they flee and hide in a warehouse, where they come up with a plan to stop the tornade, namely, to blow them up.

Eventually, Fin himself destroys the last tornado with a bomb attached to his car, and all the sharks begin to fall on the ground.

Fin and his childhood friend Skye are trying to destroy them with bombs, just like last time, April comes from the hospital with a circular saw instead of a hand.

(Referring to Ash from Evil Dead) Skye sacrifices herself, allowing Finn and April to destroy Shark Tornado.

Following the events of the previous film, Fin and April travel to London with their young son Gil to attend a NATO meeting regarding the escalating sharknado threat.

They discover a shrine dedicated to an ancient shark god and collect an artifact, which has the unforeseen consequence of unleashing a new type of sharknado with a dimensional vortex inside it.
