Henry Rios is a gay Latino defense lawyer determined to serve clients that his straight, white colleagues refuse to represent. After falling for a recovering drug addict named Paris, Rios is devastated when his lover is killed in a way that the police call “accidental.” But Rios sees the signs that point to murder as the cause, and he starts his investigation by unraveling the family secrets alluded to by Paris while he was still alive.
