Daybreak (1933)

Fishing village girl Ling Ling sets off to look for her cousin in Shanghai. She soon finds out that Shanghai is a city full of vice: she is raped, sold into prostitution, and later becomes a socialite who uses her earnings to help others. She still waits at the pier in the hope that she sees her sailor lover return from the sea one day. By then, the revolution is starting to gain momentum.
