The plot of "Umberto D." culminates in a series of desperate acts driven by Umberto's impending eviction. After returning from a brief stay in the hospital (a tactic to get free bed and board), he discovers his landlady has begun renovations, essentially destroying his room. Worse, his dog Flike, left in the care of the maid Maria, has run away. Umberto's frantic search leads him to the city pound, where he reclaims Flike just before the dog would have been euthanized in a harrowing scene.
With no home and no prospects, Umberto sees suicide as his only escape. However, his profound love for Flike creates a final, agonizing dilemma: he cannot bear to leave the dog alone and uncared for. He tries to give Flike away, first to a couple who board dogs and then to a little girl, but he is unable to part with his only companion. This leads to the film's climax at a set of train tracks. Holding Flike tightly, Umberto walks toward an oncoming train, intending to end both their lives. In a moment of terror, Flike struggles and leaps from his arms, running away. Umberto's desperate cries for the dog break him from his suicidal resolve. Flike, initially frightened and distrustful, cautiously returns. The final scene shows the two in a park, Umberto trying to coax Flike to play. They reconcile, and walk off together down a tree-lined path. The ending offers no solution to Umberto's poverty but affirms his choice to live, his bond with Flike having pulled him back from the abyss. The ambiguity lies in whether this is a lasting resolution or merely a delay of the inevitable tragedy.
