On a riverbank, Alice spots a White Rabbit in a waistcoat passing by, exclaiming that he is "late for a very important date". She gives chase, following him into a large rabbit hole. She sees him leave through a tiny door, whose talking knob advises her to shrink to an appropriate height by drinking from a bottle marked "Drink Me". She does so and floats out through the keyhole in a sea of her own tears, which she cried after eating a biscuit marked "Eat Me" caused her to grow very large. As she continues to follow the Rabbit, she meets numerous characters, including Tweedledum and Tweedledee, who recount the tale of "The Walrus and the Carpenter".
Alice tracks the Rabbit to his house; he sends her to retrieve his gloves after mistaking her for his housemaid. While searching for them, she eats another cookie marked “Eat Me” from his cookie canister and grows large again, getting stuck in the house. Thinking she is a monster, he brings the Dodo over to help him get rid of her. When the Dodo decides to burn the house down, Alice escapes by eating a carrot from the Rabbit's garden, which causes her to shrink to three inches tall, and continues following him. Along the way, she meets a garden of talking flowers who initially welcome her with a song, but then mistake her for a weed and order her to leave, followed by a Caterpillar, who becomes enraged after she tells him she is distressed at her current height, as he is the same height, and turns into a butterfly. Before leaving, he advises her to eat a piece of his mushroom to alter her size. She does so and manages to return to her original height, and continues following the Rabbit.
In the woods, Alice meets the Cheshire Cat, who advises her to visit the Mad Hatter or the March Hare to find out where the Rabbit is. She encounters both, along with the Dormouse, at the Hare's house having a mad tea party and celebrating their "unbirthday". They celebrate her unbirthday too, but she becomes frustrated at them interrupting her every time she tries to speak. As she is above to leave, the Rabbit appears, continuing to exclaim that he is late; the Hatter examines his pocket watch and says it is "two days slow", and attempts to “fix” it by filling it with food and tea but ends up having to destroy it after it goes "mad". The Rabbit laments that his watch was an "unbirthday present", and the Hatter and Hare sing "The Unbirthday Song" to him before throwing him back into the woods. Fed up with the nonsense, Alice decides to go home, but her surroundings have completely changed and she gets lost. Fearing she is lost forever, she sits on a rock sobbing.
The Cheshire Cat reappears and advises Alice to ask the Queen of Hearts for directions home, showing her a "shortcut" to the King and tyrannical Queen's castle. The Queen orders the beheading of a trio of playing card gardeners who mistakenly planted white roses instead of red ones, and invites (or rather forces) Alice to play against her in a croquet match, in which live flamingos, card guards and hedgehogs are used as equipment. The animals and card guards rig the game in favor of the Queen. The Cat appears again and plays a trick on the Queen, causing her to fall over. She blames Alice for this, and Alice is arrested and put on trial.
At Alice's trial, the Mad Hatter, March Hare and Dormouse are called to the stand as witnesses, briefly celebrating the Queen's unbirthday and giving her a headpiece as a present, which turns into the Cat. Chaos ensues when the frightened Dormouse runs around the courtroom. As the Queen orders Alice’s execution, Alice eats the pieces of the Caterpillar's mushroom she saved and grows large again. The King and Queen order her to leave the courthouse, but she refuses and insults the Queen. As she does so, she returns to her normal size, and the Queen orders her execution. Alice flees, and the Queen, King, card guards and other characters give chase. When she reaches the small door she encountered at the beginning of the film, he shows her that she is actually already outside, asleep. She wakes up and leaves the riverbank with her sister and Dinah to go home for tea.
