After his mother flees the family home, a son turns to thieving in order to support his father, an abusive sort who is addicted to gambling.

After This Our Exile (父子, literally Father-Son) is a 2006 Hong Kong film directed by Patrick Tam.

Plot
In hopeless pursuit of happiness, Shing (Aaron Kwok) is a man who desperately attempts to hold on to the dwindling threads of his family. Once a man who had a dream, Shing has become a deadbeat gambler whose marriage is failing with wife Lin (Charlie Yeung). Shing''s machoistic ego overrides any reasonable logic for change, which forces Lin to leave Shing repeatedly. After finally managing to escape, Shing is left with nothing but his son, Lok-Yun (Goum Ian Iskandar).

Hoping in vain to pay back loansharks, Shing turns to his loving son, Lok-Yun, who has somehow retained his filial loyalty. In his most desperate hour, Shing forces his struggle of survival onto his son, Lok-Yun, through thievery and tests the strength of loyalty and the boundaries of trust in their father-son relationship. With each passing day, the bond of love is threatened with Shing''s unrepentant ways.

A young boy finds his unwavering loyalty to his loutish dad sealing a decidedly grim fate in Hong Kong director-turned-editor Patrick Tam''s first directorial effort since his 1989 thriller My Heart Is That Eternal Rose. There was a time when Chow Cheong-shing (Aaron Kwok) was considered a smooth-talking ladies'' man, but many years of gambling have turned him into a bitter and abusive shell of his former self. When Chow''s admiring young son (Gow Ian Iskander) reveals to his father that his mother is packing her bags and planning a hasty getaway, the enraged Chow delivers a merciless beating to the woman that leaves father and son to fend for themselves. Now forced to resort to petty thievery as a means of helping dad pay off a series of lingering gambling debts, the young boy soon ends up locked away in a juvenile-detention facility. Soon thereafter, when Chow drops by to visit his son, the boy launches a vicious attack on his father that drives the pair apart for more than a decade. Years later, Chow''s son has grown into a man, and is suddenly stricken with an overpowering bout of nostalgia and that leads him back to his old hometown and the quiet streets of his youth. Just then, far off in the distance, the emotionally scarred son catches a glimpse of a man who appears to be his father.
