He's a Woman, She's a Man

Wing is a sassy girl who deeply idolizes Rose, a pop singer, and Rose's boyfriend, top record producer and song-writer Sam. Rose has been groomed by Sam, achieving stardom and international acclaim. With her success, Sam decides to try his hand at bringing up a male singer. He decides to announce a country-wide, males-only talent search, much to his former protegée's chagrin.
Wing, desperate to meet her idols, seizes this opportunity and enters the contest disguised as a male. Her childhood friend trains her to perfect this whimsical idea.
