May is a high school student who is struggling to cope with the death of her brother. She turns to lucid dreaming as a way to escape reality, but the line between dreams and reality starts to blur.

An episodic film which the director recounts four of his own dreams: Don wants to repay his debt by arranging a fake wedding; Fan, a white collar, learns to let go of his ego after struggling with love and work; a writer named Tong reunites with her long-lost mother; a driving instructor, Chung, is inspired by four 'ghost ladies' and starts to believe again in his musical talent.
