Leo Cruz, a disgraced physicist at Fermilab, accidentally activates his "Eclipse Engine" during a solar eclipse, pulling a terrified cowboy named Jebediah Cole from 1870 Kansas into a modern lab. With federal agents closing in, Leo and his assistant, Mina, must use the unstable device to smuggle Jeb—and themselves—back to his time to build a new machine and send him home for good. Stranded in the past after a chaotic effort, Leo chooses humanity over science, destroys his creation, and finds an unexpected new beginning on the Kansas prairie, keeping a world-changing secret buried.
