L'histoire se déroule cinq ans après les événements de Sharknado 3. La tempête porteuse de requins tueurs est de retour et la cible des squales est à présent Las Vegas. Après avoir ravagé la ville, le Sharknado se déplace et frappe plusieurs états du centre des États-Unis, sans façade maritime, qui n'ont pas l'habitude des cyclones se formant au-dessus de la mer, mais plutôt des tornades continentales.

Toute la famille Shepard, enfin réunie, va devoir unir ses forces pour en venir à bout.
