Rapunzel

Billy Jane Brooke is a successful tennis player nicknamed 'Rapunzel' because of her long hair. Her overprotective mother/manager surrounds Billy Jane with female bodyguards and prevents her from interacting with men. Eastern European player Jimmy Stojkovic, who is very bad at the game, is convinced by his father to compete under the guise of a woman, taking the name Martina Stojkovic, for better chances of winning. Billy Jane befriends Jimmy and inspires him to start playing well. Eventually, the two begin a 'lesbian' relationship, right under the nose of Billy Jane's mother.
