'Spike' Shannon, a pugilist by occupation, signs to fight a 10-round bout, with another young knight of the ring. A contract is drawn and 'Spike' and his backers leave the office of the promoter. On the street they encounter a young couple, evidently at outs, but which proves later, upon the girl's explanation, to be a flirtation, in which she has no desire to take part. The masher has insolently insulted her. 'Spike' takes in the situation at once and with his strong right arm knocks the dude sprawling.
