High school student Juno (Ellen Page) is a grinch, a lovely elf, who is going through the transformation from puberty to adulthood. On this day, she suddenly decided to taste the forbidden fruit with the handsome track and field player Brick (Michael Cera). Juno has gotten into a big trouble this time. She accidentally got pregnant, and the trouble that follows can be imagined. It is obviously too early to talk about marriage with Brick, but Juno does not want to have an abortion. She discussed with her friends and decided to give birth to the child and then give it to a kind couple to raise. However, her parents eventually learned of Juno's secret, and the reaction was not as bad as Juno expected-the family united because of the child in the belly, discussed strategies together, and shared the bitterness and joy of pregnancy for her. However, Juno is a super young mother after all. How to deal with all this at a young age may have to go through a spiritual transformation.
