Happy Union 2

Wong Tai Hoi as a plaincloth patrolman in a department store turns out to be his turning point. Disguised as a robot on his anti-shop-lifting beat at the toys department, Wong is mistaken as a human size innovative toy by PO PO, the only child of a wealthy businessman Tsoi Tak Chow. Wong is brought home as PO PO's birthday present. PO PO is so overjoyed with his most memorable birthday party that Wong tries his best to bring amusement and laughter to the kid. Wong volunteers to be the scapegoat for erasing Tsoi's most valuable video tape recording memorable moments of PO PO's late mother. Tsoi is extremely upset that Wong is dismissed on the spot. PO PO feels miserable and lonely that he runs away to look for Wong. Tsoi and Wong are both worried. The unhappy father offers million dollars to find his beloved son. Despite certain complication, Tsoi honours his award to Wong.
