When her husband Carlos surprises her with an unforgettably romantic getaway, Monica knows her husband is still very much in love with her. But an unexpected package turns her life upside down. Angela on the other hand has a warped perception of men. Her last husband of five years cheated on her during the course of their marriage. Then she meets Carlos and she will stop at nothing to get him for herself — even if that means destroying her life and another woman’s family.
