Li Ching - the best actress of her era - play Ah Chiao is a girl from a rural village stranded in the city, who befriends a kind-hearted transient and a retired actor. They are poor, but they are happy. Although her fortune changes for the better when she becomes a singer, she ultimately learns money can't buy happiness.
