Sent into a drunken tailspin when his entire unit is killed by a gang of thrill-seeking punks, disgraced Hong Kong police inspector Wing needs help from his new rookie partner, with a troubled past of his own, to climb out of the bottle and track down the gang and its ruthless leader.
When the Ronin Gang robs an armored car, three cops — Chan, Fong and Wai — go on the warpath. Each has a personal interest in bringing down Ronin leader Tien: he killed Chan's fiancée, humiliated Fong and kidnapped Wai's brother.
An overwhelming pro-democracy movement in Hong Kong (also described as the Occupy Movement or the Umbrella Revolution in the region) in 2014 has devastated many families in the city. A veteran journalist father, a policeman son and an activist daughter are living in a torn society of Hong Kong.

In philately, "tête-bêche", or head-to-tail in English, is used to referred to a pair of generic stamps which is inverted in relation to one another, either through a printing error or intentionally. The stamps are of special value only when they are unseparated. Metaphorically, "tête-bêche" can precisely reflected the portrayed family's tricky situation, that different role-plays or value judgments can lead to sparkling tension among family members, yet somehow the old saying of "blood is thicker than water" prevails.
