Low-budget 'creature-feature' horror. When Annie (Emmanuelle Vaugier), the alcoholic sheriff of a desolate New Mexico town, arrives at the scene of a mysterious accident, she is puzzled to discover a crab-like leg stuck to the grill of a burned-out vehicle. It later transpires that an archaeological dig has unearthed a murderous monster that's been trapped underground for 900 years and is now very, very angry with the human race. Teaming up with a group of stranded civilians, Annie must find a way to stop the beast before it wipes out everything, and everyone, in its path.

Gareth Edwards directs this ultra-low-budget indie sci-fi film. Six years ago, a NASA probe holding samples of alien life crashed over Central America on its return journey to Earth. Soon after, evidence of a new life form appeared and half of Mexico has been quarantined ever since, having being designated an 'infected zone'. Now, cynical American press photographer Andrew Kaulder (Scoot McNairy), who has entered the territory in the hope of capturing the 'monsters' on camera, finds himself escorting his boss's daughter Samantha Wynden (Whitney Able) to safety across the US border after she is injured in a monster attack.
