In quiet Elmwood Heights, Ohio, unremarkable history teacher Harry Jenkins accidentally creates a device that fractures time, letting him glimpse and tweak alternate futures. Desperate to reclaim his lost marriage and fix past regrets, he nudges small moments—reviving a dream car, rekindling love with ex-wife Martha—but each change ripples unpredictably, erasing what he cherishes most. Through vanishing objects, reversed clocks, and haunting visions, Harry learns that chasing “better” tomorrows risks losing today. Choosing presence over perfection, he lets the fractures heal, embracing an imperfect but authentic life with Martha. A humorous, heartfelt tale of love, regret, and the courage to stop rewriting the past.
