Head stork and boss Hunter (Kelsey Grammer) decides to stop delivering babies and start delivering packages instead for global internet giant Cornerstore. Junior (Andy Samberg), the company’s top delivery stork, is about to be promoted when he accidentally activates the Baby Making Machine, producing an adorable and wholly unauthorized baby girl.

Desperate to deliver this bundle of trouble before the boss gets wise, Junior and his friend Tulip (Katie Crown), the only human on Stork Mountain, race to make their first-ever baby drop – in a wild and revealing journey that could make more than one family whole and restore the storks’ true mission in the world.
