A lone time traveler from the year 2035 must solve a riddle that may save his people....but it may take him to the brink of madness. After the world's population is devastated by a killer virus, survivors must live in the dank underground communities. Cole "volunteers" to travel into the past to obtain a pure virus sample, thereby helping scientists develop a cure. Along the way, he crosses paths with a beautiful psychiatrist and a one-card-short-of-a-full-deck mental patient. But the race is on, as Cole searches for The Army Of The 12 Monkeys, a radical group linked to the deadly disease.
