Caroline Sterling enjoys executive prosperity and a comfortable suburban residence with her beloved young daughter Abby. Hoping to assist an old family acquaintance facing poverty, Caroline's kindly mother Diane invites Brenda Jenkins and Brenda's daughter Jessica to move into the estate as paid household managers, completely misjudging their greedy character.
The insolent newcomers treat the luxury residence like personal territory, pawning valuable antiques, inviting rowdy companions, and systematically looting Caroline's private vault. When Caroline finally demands an audit of the household expenditures, Brenda and Jessica execute an audacious abduction of young Abby for millions in ransom, triggering an intense police trap to save the child.
