In the film, lead characters Fin and April travel around the world instantaneously by going through portals at the top of tornadoes in order to save their son Gil, who has been swept up in a sharknado.

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.

Orion and Electra are members of the Sisterhood, as is Fin's cousin Gemini, who is supervising the ship carrying the nuclear waste left behind from the nukenado at Niagara Falls.

Fin and April end up in Rio de Janeiro, where they meet another member of the Sisterhood at an old church and learn the ancient myths behind the sharknados and the vortex, being told that "the Earth has many portals."

An art thief steals the artifact during the meeting, leading to a car chase that ends up in the Colosseum in Rome, Italy when a sharknado teleports both vehicles.

However, the sharknado they summon instead teleports them to the Pyramids of Giza in Egypt, where they find hieroglyphs indicating that the Egyptians also knew of the shark god and the vortex, which is inside the Earth's core.

Just as everything seems to be back to normal, however, the mechanism reverses and the vortex energy erupts from the Earth, triggering a global sharknado that consumes the entire world, killing Gemini who is still in Tokyo.

Club gave the film a grade A, and wrote: "Somehow, Sharknado 5: Global Swarming pulls the franchise back from the brink and returns it to what it's supposed to be: fun to watch.
