Retrograde

Val and Alex make a living as modern-day treasure hunters in a dystopian future. They strive to find long-forgotten technology from past civilizations and subsequently sell it. While exploring many years‘ worth of abandoned laboratories, Val accidentally activates an experimental device that transports her to seemingly random locations at random intervals. She is unable to turn off the device, so she communicates with her senior colleague Alex through a transmitter to figure out what to do. Another problem for Val is that by activating the device, she also triggered planetary defense, including patrolling drones that can quickly neutralize her if they find her. Eventually, Alex discovers that this device is extremely valuable and there is only one way to deactivate it in order to sell it on the black market. That option is to kill its current carrier.
