Miriam, a streetwalker, is evicted from her San Francisco boardinghouse and, down to her last $3, meets Geoffrey, an intoxicated society fellow trying to forget a broken heart. Geoffrey likes Miriam and, on a whim, takes her to the church where his lost love, Valentine, is being married to wealthy Moreland. Geoffrey becomes greatly attached to Miriam and rents her an apartment. Miriam falls deeply in love with him and becomes desperate when the heartless Valentine vamps her way back into his life. Miriam attempts to return to the streets only to discover that, deeply in love with someone for the first time in her life, she cannot give herself to another man. Miriam then contrives to show Geoffrey that Valentine is a schemer who loves only money, and Geoffrey, come at last to his senses, takes Miriam in his arms.
