I thought with Williams as the lead the rest of the cast would be low budget level actors but they all do a fine job, particularly McCoy who was Dr Who few years after Tom Baker. It has the usual idiot trope consisting of an utter tool, a mild tool, the coward that gets roped into dumb things by his tool friends, and the girlfriend that didn't want to be there in the first place. Follows a fairly standard formula of a house robbery gone wrong but without being predictable and it ramps up the tension quite well as the violence escalates. Enjoyable thriller overall.
