The Tunnel Under the World

On the morning of June 15th, Guy Burckhardt wakes up screaming from a dream of an explosion, and the day only gets stranger. The cigarette stand sells a brand he has never heard of, the elevator plays jingles for products nobody knows, and all of Tylerton seems to be selling something.

The next morning it is June 15th again, and nobody else remembers a thing. Burckhardt finds a metal shell hidden behind his cellar walls, and a frightened man named Swanson who has been hiding from the repeating day for weeks. Together they find a tunnel running out of town, and they mean to follow it to whoever is running Tylerton.
