T-Minus will be adapted from the Philip K. Dick sci-fi 1974 short story A Little Something for Us Tempunauts. In that story tempunauts aka time travelers from the U.S. are sent a few days into the future rather than a century as planned. They learn their return from the future was fatal to them. They’re also trapped in a closed time loop, and the group deliberates whether to break out of it.
