A poor but hopeful boy named Charlie Bucket lives with his loving family in the shadow of the mysterious Willy Wonka's chocolate factory, which has not allowed visitors for many years. When Wonka announces a contest that grants golden tickets to five lucky children, giving them access to a tour of his secretive candy paradise, the world erupts in a frenzy to find these rare tickets hidden inside Wonka chocolate bars. Charlie dreams of being one of the lucky ones, but his chances are slim due to his family’s financial constraints that limit him to only one birthday chocolate bar a year. Despite the odds, Charlie miraculously unearths a golden ticket, igniting excitement and wonder in the hearts of the Bucket family.

Accompanied by his Grandpa Joe, Charlie joins four other peculiar winners: the gluttonous Augustus Gloop, spoiled Veruca Salt, competitive Violet Beauregarde, and television-obsessed Mike Teavee on the promised tour. Willy Wonka’s factory astounds with its fantastical inventions and edible delights. However, it becomes apparent that each room in the factory tests the children's obedience and morality, as the group witnesses the consequences of poor behavior. The eccentric Wonka leads them through a series of marvelous yet cautionary experiences, revealing the factory's magic while subtly probing the character of each child guest.
