On an ordinary night in an ordinary year, Tommy Llewellyn's doting parents wake in a home without toys and diapers, without photos of their baby scattered about, and without any idea that the small child asleep in his crib is theirs. That's because Tommy is a boy destined to never be remembered. On the same day every year, everyone around him forgets he exists, and he grows up enduring his own universal Reset. That is until something extraordinary happens: Tommy Llewellyn falls in love. Determined to finally carve out a life for himself and land the girl of his dreams, Tommy sets out on a mission to finally trick the Reset and be remembered. But legacies aren't so easily won, and Tommy must figure out what's more important—the things we leave behind or the people we bring along with us.
