In a peaceful English garden, a young girl named Alice becomes bored with her history lesson, led by her sister. Seeking adventure, she follows a waistcoat-wearing White Rabbit down a rabbit hole, tumbling into the nonsensical and magical world of Wonderland. Alice's curiosity and desire for exploration send her on a journey of bizarre encounters and transformations. She grows and shrinks in size after consuming items labeled "Eat Me" and "Drink Me," finding herself too large to follow the rabbit through a tiny door, and too small to reach the key resting high above her.

As Alice continues her quest to pursue the White Rabbit and find her way home, she meets a plethora of eccentric inhabitants such as twin brothers Tweedledee and Tweedledum who recount the whimsical tale of "The Walrus and the Carpenter." She receives cryptic advice from a languid, smoke-blowing Caterpillar and attends a "very merry unbirthday" tea party hosted by the madcap duo of the Mad Hatter and the March Hare. In each interaction, Alice is challenged by the peculiar rules and the illogical nature of Wonderland. Her attempts to adapt to the erratic world around her often lead to frustration and bewilderment as she realizes that the creatures she encounters have very different perceptions of the world.
