"When a highly-trained female spy breaks her leg just before beginning an undercover mission as a nanny, Emily Abbott, coffee barista, is asked to fill in.
Chatter suggests a guerrilla group is plotting the assassination of a South American diplomat while he and his family are in the U.S., and that the assassin may actually be one of his protection detail.
As nanny to the diplomat’s four young children, Emily will be perfectly positioned to keep an eye on things and report back to ICS, the spy organization Brent Peterson works for.
