Brought up in an impoverished family, and kicked out of school in his teens, Thongs found himself on the wrong side of the tracks despite being nimble-footed and neat-fingered. Spurned by his family and hounded by debtors, he is goaded by his greedy landlord to collaborate in harebrained heists. Together with the agile and opportunistic Octopus, the trio kidnaps the baby grandson of a tycoon. However, due to some unexpected glitches, they fail to hand him over to the triad as planned.
