As he rummages through his father's belonging, he finds that he has been left a note from his father that he has been left a key to a rental mailbox. Inside this mailbox, Shel finds that his father has created time machines in the form of Q-pods, a hand-held device. Michael has asked that these devices be destroyed, but Shel has a better use, searching for his father in time. So Shel goes back in time to warn his father that he will disappear in the next few days. So Michael decides to leave and come back in two weeks saying he was on a work-related trip. Michael, however, does not return and Shel is worried. Shel, having no experience in foreign languages, enlists the help of a friend who teaches ancient languages at a university, David Dryden, to search through the time stream.
