Shortly before Christmas, Walter (Jonathan Goldstein (actor)) and Audrey (Nancy Sullivan (American actress)) decide to leave home for a tropical vacation. Their children Drake (Drake Bell) and Megan (Miranda Cosgrove) come home while Josh (Josh Peck) shows them his snowman air balloon decoration, which Megan sabotages. Later at the mall, Drake tells Josh that he will be throwing a Christmas party on the roof of his workplace the Premiere, which Josh is unsure of, but Helen (Yvette Nicole Brown) approves. Helen then hands Drake a Santa costume to wear in the mall. While hiding from a woman looking to kiss him, Drake meets a little girl named Mary Alice (Bailee Madison) who says she and her family want the best Christmas ever. He makes an unbreakable promise that he will make it so.
