On 28 December 1999, the citizens of New York City are getting ready for the turn of the millennium. However, Satan decides to crash the party by coming to the city and searching for his chosen bride — a 20-year-old woman named Christine York. The world will end, and the only hope lies within an atheist named Jericho Cane.

Teenager Natalie Canton's world is turned upside down when her mother loses her battle with cancer on Valentine's Day. Natalie clings to a frail white rose as she struggles with her tragic loss. While visiting her aunt, Natalie drops the rose in a riding corral and returns to find that hope has blossomed in its place. A pure-white horse stands where the rose fell. And as Natalie rides and cares for Rose, the teenager learns life-affirming lessons and discovers that love is forever constant.
