The murder of an adolescent girl from Mexico, found dead in the Los Angeles River, proves difficult and painful for Brenda and her team. At first, a known sex-offender seems the likely candidate, but questions arise about why the girl and her mother were brought to the US, leading the investigation in another direction.

Three wealthy, spoiled and unruly children become the target of Brenda's investigation when their stepmother is murdered and the family butler seemingly commits suicide shortly thereafter. Riding heard on the trio is their family attorney, who cleans up their messes and provides them with alibis.
