As the Smurfs get ready for the Blue Moon Festival, Papa Smurf sees in his cauldron a vision of Clumsy Smurf reaching for a dragon wand and the Smurfs in cages while Gargamel laughs. Not wanting this vision to come true, Papa Smurf disallows Clumsy to pick Smurf Roots. Clumsy disobeys Papa and ends up unintentionally leading Gargamel and Azrael to the village. The Smurfs all flee for their lives while Clumsy unknowingly runs towards the Forbidden Falls, with Papa Smurf, Smurfette, Grouchy, Brainy Smurf and Gutsy running after him. They find him at the edge of a cliff, and while trying to help him up, they are sucked into a gigantic vortex that spirits them to present day New York City. To make matters worse, Gargamel and Azrael follow them through the vortex. The Smurfs end up in the apartment of Patrick and Grace Winslow, a married and expectant couple, and their Basset Hound Elway. After introducing themselves and explaining their situation, the Winslows befriend them and allow them to stay in their apartment. The next day, needing to find a "star gazer" (a telescope), the Smurfs follow Patrick to his workplace at Anjelou Cosmetics, misunderstanding the previous explanation of his job as fortune-telling. He calls Grace to pick them up.
