On the eve of the Battle of Shiloh, Union soldier Tyler Sheridan has a premonition he is going to die. That night, he writes an epic anti-war poem called "Never-ending Night". The next day, a cannonball explodes in front of him, but rather than walking through the gates of Heaven, Tyler steps into a modern-day Civil War reenactment. Confused by a world he can't comprehend, Tyler has no choice but to rely on a beautiful and fascinating photojournalist for help. As Stacy Sutton watches Tyler emerge from the rising smoke of faux cannon fire, she's amazed by the authenticity of his uniform and demeanor - and then he claims to be from the nineteenth century, a mere delusion according to doctors. But Stacy's not convinced Tyler is delusional and sees helping him as her second chance - an opportunity to atone for the death of her partner...and her past. As the mystery surrounding Tyler's appearance deepens, it threatens any hope they have of a future together, and Stacy finds she must discover whether the man she loves is a traveller through time or a mad man lost in his own delusions.
