CGI effects wizard and versatile cinema Renaissance man Toby Wilkins directed this shocker, which is set in and around a remote gas station, where a vicious, virus-like entity invades the body of human victims and instills in them an unquenchable thirst for human blood. On their way into the wilderness for a romantic weekend alone, a young couple is carjacked by a desperate escaped criminal and his devious girlfriend. Later, as the mismatched couples head ever deeper into the woods, they unknowingly become targeted by a parasitic creature that absorbs the corpses of its human victims. The situation goes from bad to worse when the four travelers seek shelter at an abandoned gas station, and the insatiable creature begins taking them over one by one. With no means of telling who's been infected and who can still be trusted, the prospect of anyone escaping with their lives grows increasingly dim with each passing minute.
