Three years after the first film, Stuart Little questions his abilities following a disastrous soccer match alongside his brother George, who accidentally kicked him with a soccer ball despite said kick scoring the winning goal for their team. Stuart's relationship with George is strained further after he accidentally crashes a model airplane they were working on in the city park. Stuart's father, Frederick, tries to encourage him, telling him that "every cloud has a silver lining." Later, an apparently injured canary named Margalo falls into Stuart's roadster on his way home from school. Stuart takes her home and introduces her to the Little family, where he invites Margalo to stay with them for a while, to which she accepts. However, Margalo is secretly assisting a peregrine falcon aptly named Falcon to steal valuables from households upon earning the homeowners' trust. Orphaned as a fledging, Margalo assists Falcon in exchange for a home, but Margalo grows reluctant to steal from the Littles. Unable to concentrate on her assignment for Falcon, Margalo becomes close friends with Stuart. Falcon eventually loses patience and threatens to eat Stuart unless Margalo steals Eleanor's wedding ring. Concerned for Stuart's safety, she reluctantly complies. When the Littles discover that the ring is missing, they think it has fallen down their kitchen sink drain. Stuart offers to be lowered down the drain on a string to get it, but the string breaks while he is down the drain. A guilt-stricken Margalo saves him, then leaves the Littles' house the following night to protect Stuart. Upon realizing Margalo's disappearance, Stuart assumes she has been kidnapped by Falcon and decides to rescue her with the Littles' cat Snowbell. Before he runs away from home, Stuart asks George to lie about his whereabouts to his parents while he is gone. With the help of Snowbell's alley cat friend Monty, Stuart and Snowbell discover that Falcon lives at the top of the Pishkin Building. There, Falcon reveals to Stuart that Margalo works for him, stole his mother's ring, and faked being injured. When Margalo tries to reassure Stuart that she really is his friend, Stuart begs her to come home with him. Unwilling to lose his asset in Margalo, Falcon then attempts to kill Stuart by dropping him from the top of the building, only for Stuart to land in a passing garbage truck before he ultimately gets knocked unconscious upon impact. Falcon traps Margalo in a paint can as punishment for befriending Stuart, but Snowbell manages to reach the top of the building while Falcon is absent and releases her. Regaining consciousness on a garbage barge and seemingly losing hope, Stuart sadly considers giving up until he finds George's broken yet still-functioning model airplane on the barge, repairs it with various pieces of junk, and uses it to return to Margalo. Meanwhile, the Littles discover that George has been lying about Stuart's whereabouts and demand to know where he is. George tries not to break his promise, but when Frederick tells him that Stuart's safety matters more, George tells them that he is at the Pishkin Building but is still in big trouble for lying. Falcon attacks Snowbell, but Margalo declares her independence from him and attempts to flee with Eleanor's ring. Just as Falcon catches up, Stuart catches Margalo in his plane. The Littles follow them by the New York City Taxi as Stuart and Margalo fly through Central Park, with Falcon in hot pursuit. Eventually, knowing they cannot outrun Falcon, Stuart decides to attack him directly. Using the glare of the Sun reflected in Eleanor's ring to temporarily blind Falcon, Stuart jumps out of the plane just before it crashes into Falcon. Margalo catches Stuart, and they reunite with the Littles to return home. Falcon, crippled and no longer able to fly, falls out of the sky and lands in a trash can where Monty is searching for food. Sometime later, Margalo says goodbye to the Littles and leaves to migrate south for the winter. After this, Martha, George and Stuart's new sister, says her first words, "Bye-bye Birdie", much to the delight of the family, who celebrate before heading into the comfort of their home.
