As a series of burglaries plague an upscale, gated community, handsome detective Mike Logan goes undercover as a nanny, infiltrating the neighborhood and investigating the crimes. When the Bannermans, a high maintenance family in need of domestic assistance, hire Mike as their nanny, he forms an unlikely bond with the Bannerman children (Lucas and Ava) and develops a crush on Jessie, a beautiful nanny who works nearby. Struggling in his new role, an overwhelmed Mike soon falls out of favor with the children, who sense they're in less than capable hands. Meanwhile, tensions rise as Police Captain Frank Milano grows frustrated with Mike for making little headway in solving the high profile case. Amid a scandalous mayoral election and a growing list of local crime suspects, will Mike bring the criminals to justice, while trying to win back the affection of the Bannerman children and the heart of fellow nanny Jessie?
