Fungus the bogeyman

WHEN A FROZEN PARASITIC ALIEN PLANT THAWS OUT AT A WAREHOUSE THE HORROR QUICKLY MUSHROOMS

LISTEN to your gut, before it explodes.

In director Jonny Campbell's splattery comedy horror, adapted by Jurassic Park screenwriter David Koepp from his own novel, a night guard at a self-storage warehouse has misgivings about finding the source of a strange noise: "Maybe it's something terrible?"
