On 1977, Voyager I took flight. On 2010, Voyager II sent some rather strange information back to Earth. On July, 2021, Voyager II lost contact with Earth four years before the planned date. At the start of the 26th century, civilization on Earth was isolated and held in captivity. At 10 a.m. on October 27th, 3020, humankind went extinct.

In this seemingly never-ending cycle, Harrison Clark began to look for that one glimmer of hope for both himself and humankind.
