Mathison plays Det. Mike Logan, who goes undercover as a nanny when an affluent neighborhood is targeted by a string of robberies. Logan's case gets complicated when he starts to fall for a fellow nanny (Sarah Lancaster). Additionally, the children he's charged with looking after are more than a little precocious.
Along Came A Nanny premieres Oct. 12 at 9 pm EST on the Hallmark Movie Channel.
