Sin City Law covers four true crime cases, each presented across two episodes. It offers a 360 degree perspective on each case featuring interviews with prosecutors, public defenders, killers, victims, family members and investigators. Courtroom footage is juxtaposed with behind-the-scenes segments - including how to shop for an outfit for an alleged killer on trial.

This week focuses on brother and sister teenage meth-heads, Beau and Monique Maestas of Nevada, who set out to take revenge on a duplicitous drug dealer. Armed with knives, they attacked the woman's two young daughters, killing one and leaving the other paralysed for life.

Beau pleads guilty, hoping to save his sister from a serious charge. Three years later, Beau's penalty hearing is about to begin, and Chief Deputy District Attorney David Schwartz and District Attorney David Roger are seeking the death penalty.
