Unthinkable (2007)

In the heart of a bustling city, the tenacious and overbearing Detective Jamie McDowell takes on the world, juggling the challenges of her demanding career and the responsibilities of being a mother to her 19-year old independent son Peter. Peter, a sturdy builder living alone, finds himself caught in the crosshairs of his mother's disapproval when he announces his engagement to the enigmatic Kelly Shaw, a woman he barely knows. Unswayed by his mother's apprehensions, Peter introduces Kelly to Jamie over dinner, an encounter that quickly spirals into a clash of wills between the two potent women and their protective mothers. An unexpected twist of fate transpires when Kelly, in a misguided attempt to measure the depth of Peter's affection, incites a heated altercation with her ex-fiancé, Ray Rankin in a dimly lit bar. The lovers part ways, their words echoing in the night, carrying the weight of their unresolved conflict. That very evening, a chilling discovery awaits the two mothers as they return from a night out. Kelly's lifeless body is found charred within the confines of Susan Shaw's house, her death declared the result of a deliberate act of arson. What follows is a harrowing journey for Jamie, as the clues she uncovers in her quest for justice begin to point ominously towards one prime suspect – her own son, Peter...
