Happy Together (1997)

Yiu-Fai and Po-Wing arrive in Argentina from Hong Kong and take to the road for a holiday. Something is wrong and their relationship goes adrift. A disillusioned Yiu-Fai starts working at a tango bar to save up for his trip home. When a beaten and bruised Po-Wing reappears, Yiu-Fai is empathetic but is unable to enter a more intimate relationship. After all, Po-Wing is not ready to settle down. Yiu-Fai now works in a Chinese restaurant and meets the youthful Chang from Taiwan. Yiu-Fai's life takes on a new spin, while Po-Wing's life shatters continually in contrast.
