Elizabeth aches for one more precious hour with her son who died in a senseless accident. Andy is desperate to find his first love who vanished after a whirlwind romance. Logan craves the rush of surfing and mountain climbing, yearning to reclaim the freedom he lost after a misstep landed him in a wheelchair. Brooke is looking for an hour of relief from the guilt of an unforgivable mistake. Enter Aeon Expeditions, the groundbreaking time travel invention of Mark Saunders--which allows some lucky clients the chance to spend an hour in their past.

As their paths intertwine unexpectedly, they unearth shocking secrets hidden in the shadows of their shared history: All their lives were shattered the same night on a secluded highway by the beach.
