My CEO Mother-in-Law

Sharon Xavier learns her daughter-in-law is pregnant and gifts her a car. Her son, Colin Xavier, gives the car to his mistress, Cheryl Shaw. The mistress offends Sharon with the car. Sharon discovers her son's affair and is mistaken for his wife, so she plays along to teach the mistress a lesson. At the party, the mistress learns Sharon's true identity but, with Colin's backing, acts recklessly. When Colin defends his mistress, he is stripped of his inheritance.
