While Rachel is stuck in a time loop, reliving the night of her parents' Hanukkah party, she leans on the boy her grandmother is trying to set her up with to make it out.

Five years after the events of the first film, Christmas is once again just around the corner. In a crazy turn of events, possibly brought on accidently by the brothers themselves, the director of Luke’s son Thomas’ school holiday musical steps down. Luke, desperate to make his son’s stage dreams come true, enlists the help of his brothers Taylor and Stephan. The trio also find themselves meeting their mother's new boyfriend and the brothers grapple with their own feelings about this relationship. In true Brenner brother fashion, they are all in for a Christmas they will never forget.

The movie follows Suleman’s journey starting from her decision to have one more IVF procedure to complete her then family of six, to becoming a mother of 14, having survived her life being torn apart by the tabloid media.

Luke is expecting twins, Taylor is debating a life-changing job, and Stephan is planning a wedding — all while their mom is planning to put the family home up for sale.

Through unlikely bonds formed during night shifts at a local aquarium, Tova, an elderly widow, learns of a life-changing discovery that may bring her joy and wonder once again.
