The movie is set in United States. Sonny Koufax is a lawyer who has never liked to assume the responsibilities as an adult. However, Sonny realizes that if you do something soon could be alone for the rest of his life. When his girlfriend leaves him for his immaturity, he decides to adopt Julian, a child of 5 years.
The Big Daddy is a beautiful movie, it teaches us about the true value of love and friendship.
I love it and recommend
