The Partridge Family attend a lecture by Mike Rezo, a famous mystery writer. After the lecture, they meet him, and the discussion leads to the fact that everyone but Rezo feels that his stories are more fantasy than true to life. Rezo believes that, using human nature and logic, anything is possible. In order to prove his point, Rezo offers the Partridges a deal they can't refuse. He will give them a two-hour head start and then begin looking for them; if he can't locate them within 24 hours, he will donate $25,000 to their favorite charity.
