The Stand-In Mama. She Fixes Everything

Julie is an underground fighter. Two weeks after a cage win, Gina Morgan, her long-lost younger twin sister, finds her. Gina has cancer, a cheating husband, and three kids she cannot manage. Her dying wish is for Julie to take her place and hold the family together. Julie agrees.

Gina's family is already falling apart. Henry was Harvard-bound until his father rejected his relationship with a boy. Guy spends on gym and soccer and burns money. Jenny is bullied and scared of her own shadow. Alan Morgan, Gina's husband, lives off his family trust, moved his mistress Mary into the house while Gina was away sick for six months, and schemed to take everything. Julie accepts and warns that anyone who messes with Gina answers to her.

After a makeover, Julie enters the Morgan house as Gina. Mary and her daughter Sarah are living there. Sarah frames Jenny over a spilled cup, and Alan orders Jenny to apologize. Julie confronts Alan for letting his daughter be bullied and framed, then turns on Mary and Sarah. At lunch, Mary and Sarah have no place settings. Julie tells them to leave, Alan defends them as guests, and Julie flips the table. She warns Alan and Mary to watch their step and takes Jenny to a new place.

Jenny hides her school troubles. Sarah spreads a fake photo of Jenny with an older man and dares her to prove it is not her. Then Sarah sends William, a student expelled from his last school for getting several girls pregnant, to wait for Jenny after school. Guy sees the photo, denies it is Jenny, learns William is waiting, and goes to find her. Julie also heads to the school.

William corners Jenny and taunts her that Gina is a doormat who will not save her. Julie arrives as William attacks Jenny. Later, Julie whips Gina's three kids into shape and tears Alan apart over the cheating. The truth about the switch comes out, and the three kids side with Julie. Gina pulls through surgery. Two moms, three kids, one family.
