This is a silly comedy where opposites meet and fall for each other. Martha (June Allyson), a conservative school teacher whose aunt has the power to ruin anyone who she thinks is immoral, wins a contest to illustrate a children's book written by a successful author, Greg Rawlings (Van Johnson.) When Martha finds out Greg is a drunken womanizer his publisher John McGrath is afraid she will tell her aunt who will ruin Greg's career, so he tells Martha that Greg drinks because his son is a delinquent. Then he makes plans for her meet Greg's son so she will forgive Greg. But Greg doesn't have a son, so McGrath goes to an orphanage to find a delinquent boy to borrow for a day. When McGrath is sitting on a bench at the orphanage with the principal talking about borrowing a boy to get his opinion on a children's book, a boy runs up to them screaming for McGrath to take something out of his pocket. McGrath reaches into the boy's pocket and pulls out a snake, smiling afterwards. But when he suddenly realizes that he's holding a snake, he tosses the snake away in horror. When he is told that a boy named Danny put the snake in the pocket, he knows that Danny is the delinquent boy he needs for his plan, and brings him to Greg's apartment.
I can't figure out what kind of snake it is, but it looks like it's a live snake.
