Description

A young woman, Samantha Wabash, commits suicide by shooting herself while on a bridge, staging her death to look like murder in order to implicate Lucas Bundsch as her killer. Samantha believes that Lucas is responsible for her sister's death and that by framing him for her own "murder" the police will arrest him. Her plan fails when Holmes easily deduces that her death was a suicide. Lucas is exonerated further still when he manages to pass a polygraph test. What started out as one woman's desperate attempt to get justice for her murdered sister quickly escalates into a battle of wits with a serial killer who has managed to stay under the radar for years.
