Violet is in love with Billy, a good-for-nothing rich fellow, and his aunt and uncle decide to give him an opportunity to study law in his uncle's office. Aunt buys Uncle a striped coat: a tennis blazer. He is quite horrified with it, but she insists that he wear it to the office. He hangs it on the hat-rack near the door at the office. Billy gets awfully lazy and sneaks out. He accidentally puts on his uncle's blazer and meets his sweetheart. An old gossip-monger sees the supposed uncle embracing and kissing the girl and rushes home to tell his wife. Aunt is very angry and sends for her nephew, telling him that if he will find a sweetheart he will get $500 as a reward, but the girl must also possess a fortune. She suggests the girl who was with her husband--then Billy sees the mistake. He determines to use the information in procuring the prize and tells his sweetheart the scheme. It all ends happily after many complications, and Billy and Violet marry with the $500 as a wedding gift.
