Cheung, a single mother living in an area with high crime rates, works hard to provide for her son while helping out her elderly neighbor.

Ka, a common housewife, leaves her husband after big change in the family. Then she encounters Man, who has for years blamed her father Chow for bringing to light his relationship with his lover Tracy after the accidental death of Man’s mother. And so it seems that from departures stems relationships anew, but there are in fact little to be explained in the logic of cause-and-effect for existence, death, encounters, and love.

Raymond is a boyish thirty-something content with his wife Nancy and son Kai Zhen who studies K2. Nancy decides to spur up Kai Zhen's "talents" with an onslaught of extracurricular activities. They are tickets to a handful of certificates and awards so that Kai Zhen will not be overshadowed by other kids and may receive placement in more elite schools. Disapproving of the move, Raymond hopes his son could enjoy his childhood. Nancy insists and asks Raymond to find Kai Zhen a referee for school enrolment. In the meanwhile, Raymond was sacked and had to leave his job of twenty years. A painful journey begins with his job hunt and eventual sale of his own favourite toys and pleasures. For the sake of his son, he swallows his pride and begs his old boss to be his son’s referee.
