We see Tramp for the first time when he awakens at the train station. Then, all of a sudden, he goes for breakfast. Thanks to his shrewdness, he manages to get a ham sandwich. When he runs away and wants to eat his booty, he sees a pair of puppies in the bushes that ask him for food. The dog succumbs to their requests and gives them his sandwich.
When he leaves the park, he sees from a distance Elliot, a dog catcher who wants to catch him at all costs. Mutt helps free his two friends, Peg and Bull. After he escaped Elliot, Tramp moves into Trusty's backyard.
Lady talks to him, unmindful that Tramp is impersonating Trusty. When Lady realizes, she starts barking, even though Tramp begs her to stop. When Tramp tells Lady that he will tell her the truth about the child, it is too late, because Elliot approaches the fence. When the dog catcher departs, Lady stops the Tramp, and wants to hear from him why the child would be the reason for its owners to quit paying attention to her. Lady did not believe the dog, which leaves peacefully from her yard. Tramp warns her only with words "When a baby moves in, the dog moves out".
In the next scene, Tramp rescue Lady from the pugnacious street dog, Issac. Then, he helps her to remove the muzzle from her mouth. The dogs go for a walk around the city afterwards, as Lady loses her collar and could be caught by a dog catcher. Tramp leads her to his favorite Tony's restaurant. A feeling begins to arise between the two. And then, they fall in love with one another.
Tramp shows Lady view of the city from the hill. He also reveals that he had owners who abandoned him as soon as their baby was born. Suddenly, they are found by Elliot so they run away and separate. Tramp manages to get away, but Lady is captured when she returns to help him. The dog owes Lady an apology in his own thoughts ("I'm so sorry Lady").
In the next scene, we see Tramp lurking by the pound (his intention was to free Lady from this place).
A few days later, Tramp is found by Peg and Bull, who were adopted by a nice man. The dog is completely broken, he misses Lady and it shows in his eyes.
Peg urges Tramp to confess to Lady that he loves her. The dog follows her advice, takes Bull's bone and runs to the object of his love.
The Tramp appears in Lady's garden. He gives her a bone, though he admits he stole it. Tramp tells Lady that he is sorry that he left her at the train station and owes her an apology for it.
Lady states that the dog himself said that if others are not loyal, then why should he be. Lady says she should believe him then, but Tramp tells her that no, she shouldn't believe him.
Tramp says that being free without Lady by his side is just loneliness for him. The dog states that Lady knows that he is an ordinary street dog and has no value. Lady says that Tramp has value for her. Then she tells him that she missed him, for what, Tramp says he missed her too (in this way, though not directly, they both revealed that they love one another) Lady says she goes out into the garden to howl at the moon at times.
Tramp says it doesn't have to be over. He offers her a breakaway escape and lots of adventures. The dog is sure that it is not too late for this, but he asks Lady for her opinion. Sadly, Lady finds it is too late. Tramp says she belongs to this house, that together with Jim, Darling and Lulu they're a family. Lady tells Tramp her owners rely on her and she is steadfast to them.
The dog accepts this sadly. He says that the female deserves it, which Lady replies that Tramp also deserves home and love, she regrets that together they cannot be happy.
A storm breaks out, so Jim calls Lady to come in and not get wet outside. Tramp walks out with a broken heart because he knows that the female he loves will not spend the rest of his days with him.
Lady is also heartbroken that she dismissed Tramp and deliberately broke his heart and hurt his feelings. Suddenly, she notices a rat that climbed up the ivy and entered Lulu's room. Lady tries to warn her owners, but they locked her in the bathroom, because Elliot shows up to interview Jim and Darling and tell them about Tramp.
Lady, unable to get out of the restroom, calls for help from Tramp, who did not go too far and hears her bark. The female tells him about the danger.
The dog decides to rescue tiny Lulu from the rat and sneaks into the house and into the baby's room afterwards.
Tramp looks into the cradle to see if everything is okay with Lulu. Then, he starts looking for a rat. He sees him in the mirror but the rodent jumps on Tramp's muzzle and bites him. The dog manages to dump the rat and starts chasing him around the room. The dog knocks over the furniture while he is trying to catch a rodent.
Finally, the rat climbs on Lulu's cradle and tries to jump there. Tramp, trying to dump him, turns over Lulu's crib. He catches it with his own body and is wounded, but he is glad that Lulu is fine.
At the last moment, he notices a rat holding on to the veil, so he grabs and pulls it off. The curtain and rat fall down. Tramp fights the rodent under the veil and eventually manages to maul him to death.
The dog is injured, but goes towards Lulu, wanting to calm her down. At this point, He is caught by Jim and Darling, believing that Tramp tried to hurt Lulu, they hand him over to Elliot.
Lady, wanting to save him, shows Jim and Darling the bitten rat. Then, she chases the carriage with the help of Trusty and Jock.
Lady frightens the horses off and causes the carriage to collapse. She finds a Tramp who looks dead because of the carriage and falling out of it. Lady asks him to awaken, but when Tramp doesn't do this, she seems that the dog she loves has passed on and she is devastated. She lets out a howl of despair and grief. Unexpectedly, Tramp regains consciousness. The dog states that Lady howls well, but they still have to work on its volume: ,,Pretty good, kid. We still need to work on your volume". Lady comes up to him and licks his face and wipes her mouth on his, she does it to comfort him and to show him that she loves him.
Jim and Darling show up and search for Tramp. They realize that the injury he has on his left foreleg comes from a rat bite and they understand that the dog saved Lulu, Darling says Tramp was injured saving Lulu ,,Oh, he got hurt protecting Lulu from the rat".
Elliot callously puts the dog around his neck and begins to pull him towards the pound. He's determined to put Tramp to sleep. Darling intervenes to see that Tramp is suffering from injury, and besides, she tries to explain to Elliot that the dog saved their baby from the rat.
The dog catcher insists that the dog has no collar and is unregistered, so he takes him to the pound. A woman rescues Tramp by saying that he has a home, that they are hugging him at their home.
Elliot releases the rope. Darling tries to convince Tramp, though the dog is wary. He is wounded, sore and horrified, after Elliot treated him a moment ago. Eventually, after Lady's encouragement, Tramp gets up and approaches his new owners. Elliot leaves. Mrs. Darling pulls the rope around his neck so that he can breathe freely and feel free.
After Mrs. Darling calls him "Good boy," Tramp and Lady lean their heads against the heads of the other, which symbolizes that they are together again and feel happy about it.
A few days later, it's Christmas Eve. Tramp has already been recognized as a family member. The dog receives a new, dark brown leather collar.
Tramp states that he has felt happy at home. They both lie down at their owners' feet and listen to Mrs. Darling singing "Peace on Earth" which symbolizes that both dogs will always be together.
