This play, Barrie's most successful, is the story of the boy who wouldn't grow up. It will never grow old. Peter Pan drops in on the Darling children. In spite of the efforts of their nurse, the dog Nana, he teaches Wendy and her brothers to fly. They soar with him to Never-Never Land, where Wendy becomes the mother of the lost children who live underground and in the hollow trunks of trees. Adventures with Indians and pirates follow. The pirate chief, Captain Hook, is followed by a crocodile that, having devoured the Captain's hand, seeks the remainder of his meal; but the ticking of a clock the crocodile has swallowed always warns the Captain. There is desperate war between the children and the pirates. Peter's friend, the fairy Tinker Bell -- visible only as a dancing light -- swallows the poison Hook has prepared for Peter. To save her life, Peter appeals to the audience: Do you believe in fairies?, and as the audience applauds Tinker Bell's light grows bright again. Peter leads his forces onto the pirate ship, and the desperados walk the plank. Wendy goes home, promising always to return, for the spring cleaning, to Peter's house in the tree-top in Never-Never Land.
