Meet Juno MacGuff (Ellen Page), a confidently frank teenage girl who calls the shots with a nonchalant cool and an effortless attitude as she journeys through an emotional nine-month adventure into adulthood. Quick-witted and distinctively unique, Juno walks Dancing Elk High's halls to her own tune—preferably anything by The Stooges—but underneath her tough, no-nonsense exterior is just a teenage girl trying to figure it all out.

While most girls at Dancing Elk are updating their MySpace page or shopping at the mall, Juno is a whip-smart Minnesota teen living by her own rules. A typically boring afternoon becomes anything but when Juno decides to have sex with the charmingly unassuming Bleeker (Michael Cera). Faced with an unplanned pregnancy, she and best friend Leah (Olivia Thirlby) hatch a plan to find Juno's unborn baby the perfect set of parents courtesy of the local Penny Saver.They set their sights on Mark and Vanessa Loring (Jason Bateman and Jennifer Garner), an affluent suburban couple longing to adopt their first child. Luckily, Juno has the support of her dad and stepmother (J. K. Simmons and Allison Janney). Juno's physical changes mirror her personal growth while the veneer of Mark and Vanessa's idyllic life starts to show signs of cracking. With a fearless intellect far removed from the usual teenage angst, Juno conquers her problems head-on, displaying a youthful exuberance both smart and unexpected.
