He is a homeless man (Charles Chaplin), penniless, who meets a blind flower girl, but cannot bear to stand by and watch. He tries his best to raise enough money for the flower girl's treatment. One day, he rescued a rich man, who called him a brother that night, but turned his face against him the next day. The idea of asking him for help is not working. The homeless man went to participate in a boxing match in an attempt to win a bonus, but lost miserably. Unexpectedly, he met the rich man again at this time, and the two put aside their past grudges. The rich man agreed to help the flower girl with money. After giving the homeless man 1,000 yuan, the rich man was attacked and the remaining money on his body was robbed by the robbers. The homeless man chased him desperately, but was taken back to the police station and jailed by the police because of a misunderstanding. On the other hand, the flower girl regained her sight with the help of the homeless man and opened a decent flower shop.
