A hotshot package delivering stork (Junior) and his female human partner (Tulip), work at the distribution center of an enormous online store, Cornerstore.com, situated high in the mountains. After a boy sends a letter to the company, the two accidentally create a female baby using the defunct baby factory the storks had formerly used in their original business of making and delivering babies. In order to protect the baby from the company's manager and ensure Junior's promotion to succeed him, the two set off on a journey to deliver the baby to the boy's family.
