Three Wise Men and a Baby

Luke finds a baby named Thomas at the fire station's doorstep with a note asking him to take care of him until Christmas. He decides to bring the baby to his mother's house, where his brothers also help look after him. This moment kicks off their improvised Christmas caregiving.

Barbara receives a call that their aunt has had an accident and left to visit her. She departs, but a snowstorm prevents her returning, leaving the brothers to look after the baby alone. This sets the stage for the brothers to coordinate care during the lead-up to Christmas.

Taylor initially tries to manage babysitting while his brothers work. He is clumsy at shopping and buys adult diapers instead of baby diapers, complicating care. The mix-up highlights his struggle with responsibility.

Stephan becomes the babysitter; while baking cookies with the baby, the baby cries, and Stephan focuses on calming him to the point of neglecting the cookies in the oven. The cookies burn, forcing Taylor to point out the mishap. The incident prompts Stephan to share the caregiving duties with Taylor.

Taylor and Stephan begin taking care of the baby together, and their relationship gradually improves as they work as a team. They navigate feeding, playtime, and routines while the brothers reconnect. The shared responsibility brings them closer.

Luke returns from work to find his brothers overwhelmed by the care of the baby. The next morning, he bakes cookies with the baby, showing his willingness to help and take initiative. His presence stabilizes the household.

In the evening, Stephan discovers a different baby in the bassinet and realizes Thomas has been swapped. They manage to return Thomas to his parents and exchange the babies back.

Over the next few days, they take Thomas on a Christmas market trip, go ice skating, and watch the baby laugh during the festivities. The family bond deepens as they share joyful moments with the child. The Christmas spirit grows in the house.

Their neighbor Hernandez shows off Las Vegas–style decorations and proclaims he will win the TV station prize again. The brothers feel challenged to outdo him and begin planning an elaborate display. The contest becomes a catalyst for their teamwork.

During the prize broadcast, a Christmas fire truck arrives in front of the house. The power generator overloads from the lavish lights, so they improvise a nativity play lit only by a spotlight and the truck's star. Fiona helps reset the fuses, and Hernandez is still named the winner but is impressed by their performance.

Hernandez invites them for eggnog; Barbara returns from visiting her aunt. Sophie, Thomas's mother, runs into the crowd and reveals herself. She explains the circumstances that Luke helped during Thomas's birth, acknowledging his care.

Luke and Sophie grow closer as they balance care for Thomas and their evolving relationship. Sophie expresses gratitude for Luke's support during the birth and her decision to entrust the baby to him. Their bond strengthens as Christmas approaches.

Stephan gathers the courage to confess his feelings to Susie, who has loved him since they first met. They kiss, marking a new step in their relationship. The moment closes a chapter of tension and opens it toward happiness.

Taylor visits his former workplace and apologizes for leaving suddenly. Fiona speaks to his boss on his behalf to give him another chance. He admits his mistakes and says he doesn't want to lose her again.

A year later the brothers celebrate Christmas with their girlfriends Susie, Sophie, and Fiona at Luke's house. Barbara, Thomas, and Hernandez join as friends after the competition, with Hernandez having become a friend of the brothers. The family dynamics are stronger and more connected than before.
