After taking three pregnancy tests in Rollo's (Rainn Wilson) store, Juno MacGuff (Ellen Page) discovers she is nine weeks pregnant by her close friend Paulie Bleeker (Michael Cera). She calls her best friend, Leah (Olivia Thirlby), and decides to schedule an abortion without telling her father and step-mother. Although she encounters a pro-life classmate protesting alone outside the clinic, Juno enters but becomes unnerved and overwhelmed. She returns home intent on carrying the pregnancy to term and to give the infant up for adoption.

Juno and Leah look through the Pennysaver for couples seeking to adopt children and finally come by an ad from Mark and Vanessa Loring (Jason Bateman and Jennifer Garner). Juno breaks the news of her pregnancy to her father Mac MacGuff (J. K. Simmons) and her stepmother, Brenda "Bren" MacGuff (Allison Janney), who support her decision to put the baby up for adoption. Juno and her father visit the affluent Lorings in their suburban home where the high-strung Vanessa is unsettled by Juno's sarcasm, but Juno and Mark form a bond over their shared musical interests. Mark reveals that he was once in a punk band but now writes commercial jingles. Juno teases him because Vanessa has boxed all his hobbies – Les Paul guitars, recording gear, and comic books – to a single room in the house.

Several weeks later in the winter Juno goes to receive an ultrasound with Bren and Leah, where a comment about teen mothers by the technician prompts a harsh rebuke from Bren. After the appointment, Juno drives to the Loring residence unannounced to share the ultrasound picture with them. As Mark works from home, he welcomes her and they begin to discuss their shared interests in alternative music and horror films. Vanessa returns home and is caught off-guard by Juno's presence but looks at the ultrasound with interest. Juno comes across a collection of baby items and Vanessa reveals that a previous adoption fell through which prompts Juno to reaffirm her commitment to giving them her child. Juno returns home and her stepmother admonishes her that spending time with a married man may cause problems, a concern Juno rejects, saying they are just friends. When Juno later drives to Paulie's house to spend time together in his room as they always used to, he suggests that they rekindle their relationship after the pregnancy. She rebuffs him and suggests he date Katrina De Voort instead.

When Juno is in the final weeks of her pregnancy in the spring, she visits the mall with Leah and covertly observes a relaxed Vanessa playing happily with a friend's child. She appears touched and continues to watch them even when Leah walks away. When they run into each other, Juno encourages Vanessa to touch her belly and speak to the baby. Vanessa is thrilled when she realizes the baby responds to her voice by kicking. At school, Juno learns that Paulie asked Katrina De Voort to go to prom and has a falling out with him.

Juno again visits the Lorings and is pleased that Mark is home alone. They talk about music and play each other some favorite songs. They begin to flirt with each other tentatively, slow dancing as Mark tells Juno about his senior prom. Then he reveals he is leaving Vanessa because a baby will not fix their broken marriage. Juno is upset because she wanted her baby in a stable family and storms out of the room in tears just as Vanessa arrives home, wondering what is going on. When Mark says he is unprepared to be a father, Vanessa asks him to mature and become a father to their child. Juno is thrown by this turn of events and runs out to her car. After she composes herself on the side of the highway, she drives to the parking lot of a local convenience store and writes a note on a discarded receipt. Juno leaves the note on the Lorings' doorstep and drives away. When she returns home, Mac gives her advice about finding unconditional love and being in a committed relationship. Juno realizes that she loves Paulie and stuffs his mailbox full of his favorite orange Tic Tacs that night. At the track field the next day, she admits that she loves him and they reconcile and begin a relationship with a public kiss.

Juno ultimately gives birth to a baby boy; she decides not to call Paulie because he had a very important track meet that day. When Paulie wins his meet and sees Juno is not in the stands cheering for him, he runs straight to the hospital in only his running gear. He climbs into her hospital bed to console Juno who is more distraught over giving up her child than she realized she would be. Juno and Paulie agree it is best to not see the baby because they never felt as if he belonged to them, but rather was always meant for Vanessa. Vanessa claims the boy from the nursery as Bren looks on. In the baby's nursery at Vanessa's house, Juno's note on the receipt is framed on the wall: "Vanessa, if you're still in, I'm still in. -Juno." The film concludes with a final kiss between Juno and Paulie after they sing and play The Moldy Peaches' song "Anyone Else But You".


MY VIEW ON JUNO:

It's a great film for me.. For once, it touches a bit of reality about teen pregnancy, and well, it's quite nice to see that her parents were quite supportive with her dilemma and juno manages herself well in the film.. I'll give it an 8.5/10 rating.. :)
