As a homework assignment, Andy has been given the task of creating a time capsule which reflects his family's history. For his part, the littlest Keaton has placed his baby boots in the capsule, and asks his parents and siblings to contribute mementos from their past.
Soon, the family is looking back and laughing at some of their funniest experiences together. They flash back to when Steven and Elyse went to Woodstock; when Alex went to jail with a group of feminists after feigning support for the Equal Rights Amendment; and when Mallory coached Nick in grammar to pass his high school equivalency exam.
They also recall what happened when Mallory began dispensing advice to the lovelorn in her Dear Mallory column; when Steven made a mess out of wallpapering the kitchen; and when Elyse became a blackjack fanatic in Atlantic City where she was supposed to be lecturing at a conference.
