In the 18th season premiere, deputies Marc Taub and Joseph Ensminger of the Travis County, TX, Sheriff's Office question the residents of a home that has been burglarized and we learn that someone went into the house and completely trashed it. However, there is no sign of forced entry and nothing is missing from the property. The complainant and his friend, who appear inebriated, explain that they think they know who did it, and they believe it occurred because they would not smoke enough pot with him. Deputies take fingerprints from an article in the kitchen and advise the residents to be careful about whom they hang out with. In another segment, Corporal Bev Genevish, Officer James Presley and Lt. J.T. Strickland of the Gwinnett County, GA, Police Department investigate a call about a car hitting person riding a bike. At the scene, the driver's car has run off the road, and while the vehicle's windshield and hood are both damaged, the driver claims to have no memory of hitting anyone. As the investigation continues, a bloodied young boy stumbles toward officers, but the injury has impaired his memory and he cannot remember how it happened.

When Detectives Rudy Reynoso and Juan Gonzalez of the Las Vegas, NV, Metropolitan Police Department respond to a call regarding the discovery of a human skull in a local park, they conduct an extensive and cautious search. With the assistance of a forensic anthropologist, they find additional human bones and discarded clothing in the immediate area. After an exhaustive day, the remains are identified when the serial number from a cell phone is traced to a man who has been reported missing. Another segment featuring the Las Vegas, NV, Metropolitan Police Department follows Officer Christopher Curtis responding to a domestic disturbance call. At the scene, the officer interviews a woman who claims that her unstable ex-boyfriend tried to break into her apartment. The ex-boyfriend confirms the woman's account and eventually comes to the emotional realization that he loves a woman who does not feel the same.
