The development of the plot of this comedy film is based on the well known theory of the installment plan. A young man purchases an edition of a book by the payment of $1 down, and the signing of a contract for 10 cents a week for a stipulated number of weeks. The collector appears for a first installment at the office and interrupts the young man in a little love scene with his stenographer. The second installment finds him asleep in bed. The third installment at a theater party. The fourth installment at a café lunching with a young lady. The fifth installment in a barber shop. The sixth installment as he is driving in a cab. The seventh installment while he is entertaining a number of young ladies with his vocal accomplishments. The eighth installment as he is about to catch a train, which he is compelled to miss on account of the collector. The ninth installment finds the collector sitting on the doorstep as he returns in the evening. The tenth installment he is enjoying himself at a skating rink when the collector appears. The eleventh installment he is out rowing with a young lady, and the collector, not to be evaded, plunges into the water after him. The last installment the collector invades a church as the young man is about to be married. The young man pays the debt in full; then returns to his bride, who has fainted at the interruption, and she discards him and leaves the church. Every situation in this film is excruciatingly funny. From the beginning of the purchase of the book till the final scene it is one continual roar of laughter.
