One of the great movie endings ever! To truly appreciate this scene you should watch City Lights (1931) in its entirety. Nevertheless, here's a brief summary: Charlie Chaplin's tramp character has been mistaken for a rich man by a blind flower girl. Charlie gets into all sorts of misadventures in order to raise enough money for an operation that will restore the girl's sight. He ends up going to prison. This scene is set months later when Charlie is released from jail. Charlie is more bedraggled than usual. (Note he doesn't have his bamboo cane!) Charlie passes by an upscale flower shop and sees the girl who now has her vision. She takes pity on Charlie and gives him a coin. She then recognizes him by the mere touch of his hand and realizes the sacrifices he must have made for her. Pass the tissues!
