A sixth home invasion in two months in the Poplar Point neighborhood of Dillingham, Washington leaves resident Jim Donahoe hospitalized, intensifying pressure on Mayor Laurel Danielson, who is struggling in the polls against safety focused rival Gil McNamara. With the lead investigator retiring, Sergeant Frank Milano unexpectedly appoints detective Mike Logan to head the case after Logan proposes going undercover in the neighborhood as a live in nanny to investigate the robberies from the inside. Working for lawyers Kevin and Lizzie Bannerman while caring for their children Lucas and Ava, Mike tries to gain the trust of the local nannies, especially Jessie White, while balancing the challenge of solving the crimes and learning how to be a positive role model for the kids.
