Christian Reginald Shane, is a hired assassin to kill cheating spouses. His meticulous execution has helped him avoid capture. Detective Joslyn Simms is on the case to capture the assassin.

Christian Reginald Shane, a former military operative with a dark past, has reinvented himself as a hired assassin in the bustling city of Los Angeles. His unique approach to assassination sets him apart: before executing a cheating spouse, he listens to their side of the story. If they can convince him their infidelity is justified, he spares their life on the condition they attend counseling with their spouse. Should they fail to mend their marriage, Christian promises severe repercussions. Christian believes his actions serve a greater good, helping couples confront their issues or providing justice for the betrayed. His intelligence and meticulous planning have kept him off the radar of law enforcement, leaving no evidence behind and crafting unbreakable alibis. However, his careful methods come under scrutiny when a 7th cheating spouse and their lover are found dead, and again this case seems unconnected to the others and devoid of clues. Enter Detective Joslyn Simms, one of the youngest and brightest detectives in the Los Angeles police force. Driven by a keen sense of justice and her own personal experiences with betrayal, Simms refuses to accept the deaths as random acts of violence. She begins to see a pattern where others do not, suspecting a sophisticated and elusive killer is at work. As Simms delves deeper into the investigation, Christian's troubled past and twisted sense of morality are slowly unveiled. Haunted by his own relationship failures, he sees himself as a judge and executioner, doling out what he believes to be fair retribution or a second chance for redemption. "Commandment X: Thou Shalt Not Covet" is a taut, morally complex crime drama that explores the murky waters of infidelity, justice, and redemption. As Christian and Simms' paths inevitably cross, a high-stakes game of cat and mouse ensues, leading to a climactic showdown that questions the true nature of right and wrong.—Reggie Gaskins
