“Trust No 1” (*** out of four) was a fairly engrossing action thriller about a determined cop (Douglas Rouillard) who investigates a series of brutal murders which the department thinks is the work of a serial killer but he starts snooping around and soon realizes it involves the federal government and paramilitary operations. Typical cop-and-conspiracy story is put over by Rouillard’s intense and charismatic performance and a well-sustained mood of lurking danger. A good directorial debut by Daron Niemerow and well-produced on a low budget.
