After tearing through Los Angeles and ravaging New York City, a third watery whirlwind of deadly destruction touches down in the capital of the United States of America… just as Fin is being presented with a "Golden Chainsaw" at the White House. After making a mess of Washington, DC, the Sharknado smashes and thrashes its way down the coast towards Florida, where a nine-months-pregnant-April waits for Fin.
Run like the wind! Hide where you can! The Sharknado is back and this time, the entire east coast is in the eye of the storm. Shearing winds of teeth and death will ravage the Eastern Seabord from Washington D.C. all the way down to Orlando, Florida.
