2131

In 2131, scientists discover a large metallic asteroid that will collide with the Earth seven years later, killing all sentient life. Despite their advanced technology, they don't have enough time to move the monstrous asteroid.

Desperate to save the Earth, a group of scientists led by Dr. Leonardo Hoffman uses top-secret technology to send one young time traveler to 1981 to discover the asteroid in its previous orbit.

Bruce Hayden's mission, posing as a university student in America in 1981, aims to engage the scientific community, advance technology, and divert the asteroid.

Will the past save us?
