Big Daddy

Sonny Koufax, a 32-year-old bachelor, enjoys a carefree life in New York City. Despite having a law degree, he avoids adult responsibilities and lives off a settlement from a car accident.

Sonny's roommate, Kevin Gerrity, is preparing to propose to his girlfriend Corinne. However, Sonny becomes increasingly irritated by the prospect, feeling the pressure of his friends settling down compared to his own stagnant life.

Sonny's girlfriend Vanessa decides to end their relationship due to Sonny's immature behavior. She seeks a more stable partner, leaving Sonny feeling abandoned and troubled about his life choices.

Sonny's life takes an unexpected turn when he learns that Kevin has a son named Julian. Julian arrives at their apartment with a note explaining his mother's passing, leaving Sonny with an unanticipated responsibility.

Sonny promises to look after Julian until Kevin returns, believing this will win back Vanessa. However, his inexperience as a caretaker becomes evident as he struggles to manage his new role.

To seek guidance, Sonny takes Julian to meet their social worker, Arthur Brooks, pretending to be Kevin. During this visit, Sonny discovers that Julian must enter foster care due to the circumstances surrounding his mother’s death.

Despite initial challenges, Sonny begins to bond with Julian, discovering joy and purpose in this newfound father-son relationship. This connection starts to reshape Sonny's understanding of maturity and responsibility.

As Sonny grows fond of Julian, he also forms a bond with Layla, Corinne's sister. Their budding relationship adds complexity to Sonny's life as he begins to find love amid his struggles with parenting.

Sonny faces the threat of Julian being taken away as social services discover his deception regarding his identity. This news prompts a frantic race against time for Sonny to prove his capability as a caretaker.

In a pivotal courtroom scene, Sonny and his friends rally to support him. With Layla and Corinne providing testimony, the case becomes a test of Sonny's readiness to embrace fatherhood.

Sonny courageously takes the stand to express his desire to raise Julian. His heartfelt testimony convinces his father, Lenny, of his growth and determination to be a responsible parent.

In a surprising turn, Kevin admits to being Julian's biological father during the trial. The judge grants custody to Kevin pending DNA results, leaving Sonny's hopes hanging in the balance.

Despite the custody ruling, Sonny vows to remain a part of Julian's life. He establishes a regular schedule to see Julian, solidifying their bond even after the court's decision.

A year later, Sonny has transformed into a more responsible man, having moved on and started a family. He is now a lawyer, married to Layla, and celebrates his birthday surrounded by friends and family.

At his surprise birthday party at Hooters, Sonny encounters Julian again, rekindling their connection. The event is filled with nostalgia as he also spots Vanessa, further reflecting on how much his life has changed.
