Meet Morgan, who at first seems like an ordinary cleaning lady. She’s not afraid to get her hands dirty, which is fortunate since her job involves tidying up grisly crime scenes rather than luxurious homes. During one of these clean-ups, Morgan stumbles upon a crucial piece of evidence that the forensic team missed. Her talent for interpreting blood splatter patterns draws the attention of Nick, a rookie detective assigned to the case. The two quickly form an unofficial partnership as they tackle a series of interconnected murders. As they edge closer to unraveling the mystery, their growing attraction to each other threatens to cloud their judgment. Although they manage to extract a confession from their main suspect, their emotions put them at risk of overlooking the truth, bringing them perilously close to the actual murderer.
