Police sergeants Johnson and McManus take on Los Angeles confidence tricksters. Con man Tony Wells, lining up rich widow Jessica Royce as his latest mark, sets up a false paranormal society with other charlatans to convince the credulous Jessica that her late son is speaking to her through their sham seances. When the plan leads to murder, Johnson and McManus must bring the group down before they kill again.
