Madeleine Aubry is the new concierge at the apartment house, and she's a hard-working girl. She can get no work done, because all the men insist on doing it for her. If she is sweeping out the foyer, one comes and sweeps for her; when she turns her attention to polishing the stair rail, another shows up to do the task; and when she takes the opportunity to darn socks, a third does that chore.

Max, a young man about town, splits his trousers while getting ready to go out one night. After applying some rather risky repairs without taking the trousers off, he gingerly heads off to a dinner party. Of course, disaster strikes almost as soon as he arrives, and he spends the rest of the film frantically attempting to hide the gaping tear in his trousers from the other guests.

A nanny quits her job, and convinces all the other nannies in the apartment building to go out on strike. The strike spreads to the city, with nannies everywhere abandoning their charges, in the park and in the streets. A counter-protest of abandoned babies follows.
