Willy's parents, janitors, leave the house in his care and he, of course, takes the job seriously. He starts by pushing aside a porter, who is carrying a trunk to an apartment above and a tenant who did not wipe his feet before entering the house. Annoyed by an organ grinder, Willy makes him get out in a hurry and becomes furious when he sees one of the tenants shaking a rug out of a window. Coming down the stairs, he notifies an old lady with a small dog. "No dogs in this house," says Willy. He spills some water over the old lady and lets the dog loose. It runs away, followed by its mistress. In spite of a notice that no orders will be given after ten o'clock in the morning, a few tradesmen, butcher, baker, grocer, etc., arrive and they are well received by Willy. As it is the day the rents are due, the landlord calls to collect them but Willy thinks it is not yet time and gets out a hose with which he wets everybody who has been watching him. Soon his mother returns and Willy receives proper punishment which his excess of zeal has won for him.
