Three months later, Phil and Kate Sterling have recently relocated from Chicago to Los Angeles, where Phil has taken a lucrative advertising job. Kate becomes pregnant, and gives birth to a son, Jake. The couple decide to hire a nanny to allow each of them to maintain their jobs, and interview two clients through a nanny agency: a young woman named Arlene, and a caring English woman, Camilla. When Arlene dies in a bicycling accident, Camilla is swiftly hired and becomes an invaluable member of the Sterlings' household.
