When a wealthy matriarch dies under questionable circumstances, Inspector Michael Riggs is assigned to the high-profile case. Riggs is determined to prove himself, but the dead woman's family closes ranks, and Riggs soon learns that even his police chief expects him to fail. Refusing to let the case go cold, Riggs follows the clues to the dead woman's estranged daughter-in-law, Victoria. Victoria is an unlikely society wife who evokes strong emotions within the family. Riggs needs more time, but when a second body is found in an upscale penthouse, the chief decides to pull Riggs from the case. Racing against the clock, Riggs teams up with Victoria-a gamble that could solve the case-unless Victoria is the killer.
