The film tells the story about small extraterrestrial living spaceships that save an apartment block under threat from property development.

Frank and Faye Riley, an elderly couple who manage an apartment building and café in the East Village, come under threat by a nearby property development.

When the tenants resist, Carlos and his thugs punch through artist Mason Baylor's door, intimidate pregnant single mother Marisa Esteval, and break retired boxer Harry Noble's jar of tiles.

Things look bleak until a pair of small living spaceships appear in the Rileys' apartment that evening and start repairing many of the items that were broken.

Faye buries the stillborn in a flower box the next day, but then Harry digs it up, takes it back to his apartment, and succeeds in repairing it by using parts from his beloved television set.

With Carlos unable to prove the existence of the Fix-Its that had been foiling their plans, Lacey is furious with the delays in evicting the tenants and moves to replace him.

After Harry throws him out, the tenants discover the Fix-It children are missing and go searching for them in the city while Faye stays behind with the "mother" machine as it fixes the "father".

While DeWitt flees, Carlos unsuccessfully attempts to pose as her late son Bobby to get her to leave, but succeeds in rescuing her as the fire spreads.

By the next morning, the entire building has been seamlessly restored to brand new condition, ending Lacey's demolition plans and resulting in him terminating Kovacs.

Mason and Marisa settle into a relationship while Carlos tries to start a friendship with the Rileys, with Faye finally having come to accept her real son's passing.

Some years later, the developments have been built, but this time flanking either side of the tiny apartment building, with Frank's café now doing a roaring trade as a result of the new employment brought into the area.

It was so remarkably realistic that the Sanitation Department came by and took away prop garbage one morning, potential customers stopped by to eat in the diner, and the business agent for the Plumber's Local of New York visited, demanding to know why there wasn't a permit down at City Hall for the construction."
