Mrs. Darling dozes in the nursery as her children sleep. Suddenly, the window bursts open, and Peter Pan, the boy who refuses to grow up, flies in. Seeing a grown-up in the room, he gnashes his perfect set of pearly baby teeth at her. The children's nurse Nana, a Newfoundland dog, gallops in and chases the boy out the window, slamming it shut with her paws. Peter escapes just in time, but his shadow is not so lucky. Now it is trapped in the nursery, and everyone knows he will come back for it. When he does, Wendy, John, and Michael will begin the greatest adventure any siblings have ever had.
Peter whisks the children off to Neverland to meet the Lost Boys, Tinker Bell the fairy, and Princess Tiger Lily. Together, they wage fierce battles against the evil Captain Hook and his dreaded band of ruthless pirates, whose only goal in life, it seems, is to murder Peter and his friends.
Amid the thrilling action and sweet fantasy of Peter Pan lie poignant touches of irony and tragedy. At the heart of Peter's eternal youth and innocence is his inability to learn from experience. He is always surprised when someone lies to him; he sees Wendy's flirtation only as motherly affection; and all of his friends must, of necessity, grow up and leave him behind.
