Impulsively removing a cap from an ink bottle, Beaver (Jerry Mathers) accidentally ruins some of his dad's business papers (yes, Dad does have a job!) As a result, Beaver is grounded, forbidden to leave the house all weekend. At the goading of pal Larry (Rusty Stevens), Beaver sneaks out to attend a movie. Which of course leads to the inevitable crisis -- how is The Beav going to explain the fact that he's won a new bike in a contest held at the movie house?
