The film is set in Saigon, where Khôi arrives from Nha Trang after being disowned by his family on account of his homosexuality. Đông befriends him and invites him to share an apartment along with Lam, who is—unbeknownst to Khôi—actually Đông's lover. At the apartment, Đông and Lam rob him of his money and belongings; Đông in turn abandons Lam and flees with the cash. Lam later happens upon an injured Khôi sleeping rough. In pity he returns the latter's clothes and identity papers and after a tentative reconciliation the two become friends and ultimately lovers. Lam returns to his life as a prostitute while Khôi attempts to work as a bookseller. A returning, manipulative Đông dogs the couple which culminates in Lam wounding his antagonist with a stab to the foot. Khôi eventually leaves Lam because of the latter's work as a prostitute. An increasingly desperate Lam takes to robbing his clients at knife-point; a gang of men in the employ of one such victim kills Lam at the film's climax.
