June killed her boyfriend-gorgeous, washed-up, underwear model Todd-after catching him being a rake...again. In a desperate attempt to undo her actions, she seeks out a reclusive local known for having a peculiar tunnel on his property. This tunnel, for a price, promises a one-way trip back to the previous Thursday. On the other side of the tunnel, June finds Todd is very much alive, and so is a nasty doppelganger named June Second. Additionally, June's not the only one delighted with the tunnel's secret. This other tunnel user, Julius, is keen on erasing June's existence as opposed to sharing.

Amidst this chaos, June's sole ally is an Old-World jeweler-handsome, wealthy, and unhappily married. The jeweler's consistency and robust love for June provide the only solace and stability she has as she races to survive and find her way home. Can June keep the jeweler alive, and can she take him with her when she leaves?
