A time machine's tested first time by a man in the team traveling 1 hour into the future. He returns to warn them against killings in the next hour. Is it possible to change things in the "past"? Twist after twist follow.

A group of young scientists are working on a secret project that may allow them to travel ahead in time. They test it by sending one of their own ahead one hour. He returns pleading with them to shut it down, explaining that within that hour, they will all die.

All scientists involved in the time traveling project have no clue that any problems they experience will, or has come from within their own group. With each trip through the time machine, paradoxes begin stacking up on top of each other, as any change in the time line could kill them all, or is it that not changing anything could ultimately cause their demise?—SteelRaptor24
