Bob calls on Pearl, his sweetheart, one evening while intoxicated. Pearl orders him from the house and breaks their engagement. Months pass. Bob sinks lower; he becomes a habitué of low dives and saloons. Roger Newton, the successful novelist, is now engaged in writing a novel entitled "The Tramp." He is also paying attentions to Pearl and they are practically engaged. Newton decides to go into the slums to get atmosphere. He finds his way into a saloon where Bob is playing the piano for drinks. Later, Bob saves Newton from assault. Newton, in gratitude, takes Bob home and sets him up as his secretary. Bob meets Pearl and attempts to bring about a reconciliation. Pearl refuses. This is observed by Newton who, failing to understand, grows jealous. Later Newton falls sick and is unable to finish his novel. Bob, returning home, learns of the trouble and takes it upon himself to finish it. A check comes from the publishers for $1,200 with a note saying that the last installment was the best ever. Newton investigates and finds that Bob did the work. Bob refuses the money his friend offers and congratulates both Newton and Pearl on their coming marriage.
