Jamie's illusion of his brother's perfect life is shattered when the police raid Kassi's home and haul him to the station. Kassi won't tell Jamie what's going on, but asks Jamie to help find him and his family a place on the Chatsworth during the investigation. So the Blanco family: Kassi, his wife Esther and their four feral children move in next door to the Maguires. Excited by their recent underhand windfall, Kelly and Marty decide to buy a house, but suspicions are aroused about their dirty money, and all hell breaks loose.
