The 1989 ‘one-hit-wonder’ glam-metal band Sonic Grave embark on a trip to the No-chella rock festival with their long-suffering manager in the hopes of a comeback. Making a detour to Joshua Tree to score some peyote, their carefree psychedelic pit stop soon upsets the balance of desert nature and they find themselves fighting an army of flesh-eating ants. Worse the antsy bugs keep increasing in size as the band hurtles towards their last desperate gig as they realise they must "rock" themselves out of harms way.
