Woo-sik and Hyeong-jun are two eldery waste collectors who scour the streets and back alleys of Seoul in the early morning hours for cardboard to sell. In their neighbourhood, a greengrocer by the name of Hwajin also sells her produce. For most of the ten million people living in Korea's capital city, these three are invisible. As they share a meal at Hyeong-jun's place, they realise that they have a lot in common; they are old, have no money, and are lonely. After they unintentionally become dine-and-dashers after eating at a restaurant, they develop the scam into a real art form; they leave old clothes at their table and slip out into the streets. 

 Eating at a restaurant without paying is more than just a simple criminal act in this film. It fills their previously monotonous existences with unprecedented drama and restores their dignity, giving the trio a sense of participating in life as many others do. With a lot of empathy and a pinch social realism, director Yang Jong-hyun depicts the rebellion of these three characters in a film that marries comedy and tragedy.
