During a total eclipse, the meek and dejected flower shop assistant Seymour Krelborn stumbles across a new breed of plant, which he affectionately names ‘Audrey II’ – after his co-worker crush for whom he pines. Little does he know that this strange and unusual plant will develop a soulful R&B voice, a potty mouth and an unquenchable thirst for human flesh and blood!
As Audrey II grows bigger and meaner, the carnivorous plant promises limitless fame and fortune to the down and out Seymour, as long as he continues providing a fresh supply of blood and human bodies for the increasingly bloodthirsty plant.
Just when it’s too late, Seymour discovers Audrey II’s extra-terrestrial origins and true intentions towards world domination!
