Leave It to Beaver

The movie opens with a bakery truck driving down the street, and Beaver and Wally riding together on the latter's bicycle, delivering morning newspapers. Beaver tosses the papers wildly into the air with both hands: one plops into wet cement, others land on two roofs, one in a dog's mouth, one in a birdbath, one on a cat, one in a man's leaf-vacuum nozzle, and one on a painter's head. Then the leaf vacuum explodes and throws dirt through the bakery truck's driver's side window, causing him to slam on the brakes and have his sticky pies thrown about. Beaver and Wally apologize and ride away.

Beaver has his heart set on a bike in a store window but does not think Ward and June will buy it for him. Eddie Haskell tells him that if he flatters Ward by signing up for football, he will get it for his birthday. He joins the football team and endures the practices, despite his disadvantage of being smaller than his teammates. He even goes so far as to refuse to let Ward read him a bedtime story and kiss him goodnight. He looks forward to his first game. Ward is glad he signed up for football, but his first game ends poorly when he is tricked into passing the ball to a kid on the opposing team, whom he remembered as a friend from summer camp. When he celebrates his birthday, he is presented with the new bike, as well as a computer from his great aunt.

On the first day of school, five days later, Ward and June tell Wally to accompany Beaver for a few days while he gets used to riding his new bike to there. He has a kind new teacher named Miss Landers. After school, Eddie asks Wally to come to the soda shop to see him flirt with Karen. Eddie does not want Beaver to follow them, so Wally leaves him alone at the bike rack, telling him he will be back for him. He is polishing his bike when a teenage boy comes over and asks if he can show him some cool bike tricks. He agrees and the boy shows him the tricks before riding off with the bike. At the soda shop, Karen likes Wally and not Eddie. When Wally and Eddie come out and hear that Beaver's bike was stolen, they look for it, but can't find it. During dinner that night, Beaver and Wally try to cover up for the missing bike. When Ward finds out the truth, he is upset with Beaver, but angrier at Wally because he was responsible for watching him. In Beaver and Wally's bedroom, they get into a fight, which sends Beaver's new computer flying out the open window. Wally grabs the wire and tries to pull it in, but the wire breaks, and it crashes on the ground and smashes into pieces. This results in Ward completely losing all of his patience and grounding Beaver and Wally.

After the grounding, Beaver skips football practice and studies; and Wally spends time with Karen, who breaks up with him after reuniting with her ex-boyfriend, Kyle. Beaver goes to the city and gets hit by a truck but is unharmed. He encounters the boy who stole his bike. The boy, who is Kyle's younger brother, challenges him, as a way of getting it back, to climb up to a gigantic coffee mug atop the local cafe, which he falls into and can't get out of. The fire department and Ward help get him down, Ward realizing he may be under too much pressure. He had found out about him skipping football practice and says he can quit the team, but he rejoins it. During the last game, he catches the ball and scores a touchdown, while chasing after his stolen bike. At the Mayfield Festival, he again encounters the boy and chases him. Kyle trips Beaver to help his brother escape, and Wally retaliates by pushing Kyle into a tub of fudge. Karen is also put off by Kyle's bullying and leaves him for Wally. Beaver uses a concession stand to block the boy's way, causing him to fly across a judges' table of pies set up to be judged and into an entire cart of them, resulting in Beaver getting his bike back. At home, Ward sees him polishing it, tells him that it would be safer if it stays in the house, and, at his request, reads him a bedtime story.
