In 2137, fifteen years after the events of Alien, Amanda Ripley, daughter of Ellen Ripley, is approached by Weyland-Yutani synthetic Christopher Samuels, who informs her that the flight recorder of the Nostromo was recently located by a ship named the Anesidora and is being held aboard Sevastopol, a remote free port space station owned by the Seegson Corporation, in orbit around the gas giant KG348. Samuels offers Amanda a place on the Weyland-Yutani team sent to retrieve it, so that she can have closure regarding the fate of her missing mother.
