Rose Doucette is a homicide detective, and she wants Dylan’s help with a murder investigation that she’s been asked to step back from but can’t seem to let go.

He tails the car and tries to warn Rose, but he’s too late --- the driver of the car shoots her, killing her instantly. The police are determined to pin the murder on Dylan, so he’s left with no choice but to find the killer himself. Teaming up with Rose’s widower, the pair dive into Rose’s past to figure out who could’ve wanted to kill the woman they both loved --- and what they were trying to hide.
