Sharknado: The 4th Awakens (2016) continues the tale of Fin Shepherd, the terror of flying sharks everywhere, and his merry band of washed-up costars on what must be, for some, their final go-around, as names such as Hasselhoff and Busey, Tiegs and Chrisley and Guttenberg accompany Fin in his desperate play to keep the ravaging herd of flying sharks at bay. As backstory, Astro-X, a company and not the Godzilla co-stars, has manufactured and used its nuclear Astro-Pods to suppress the sharknados, but little did they know that the sharknados were growing stronger, and so the Astro-Pods are overwhelmed, embarrassing the CEO of Astro-X.
But who knew that sharknadoes can ALSO spawn? In a fit of rapid evolution, the sharknado that has been pursuing Fin all over the landscape now becomes a firenado, fueled by an oil field strike, and then a cownado, lavanado, and a hailnado, all accompanied by the endless supply of sharks. With more to come.
But the big surprise is the return of April, Fin’s dead wife. Or, from her point of view, the return of her entire dead family. Except her Dad, a famous Evil Doctor, who has done a bad thing.
And then it all comes together at Niagara Falls, where the end of this ‘nado has been achieved, but the next … is just beginning. And, in a fit of terminal sentimentality, everyone gets rescued. Except Fin’s son’s newlywed wife, who apparently really didn’t want to continue in all this silliness.
