2122.

In the mining village of High Lonesome on LV-422, Welles discovers his buddy Harper slumped in a back street. Harper was hungover and had skipped work for the day. Welles gets Harper to his feet, and the two men go in quest of booze, suggesting that another drink could help him feel better. They move away, oblivious to the dead Facehugger lying nearby in the shadows.

When Welles and Harper arrive, Rolly and Springer are preparing to lock down the settlement's pantry for the night. Welles states that now that their ship has finished dumping supplies, his bosses have given him the authorization to buy booze for their return journey. Despite his reservations about Welles' story, Springer lets the two men in.

Harper begins to feel ill while Welles looks over the manifest and places his order. Springer takes Harper out back to show him where the toilet is. While they're gone, Rolly notices Welles sneaking a can of beer from the storeroom. Despite her rage, she does not challenge him, instead wondering whether any spaces on his spacecraft are available for her to escape LV-422. When he suggests that she might like to bunk with him, she tells him to go away.

Springer, who has returned, overhears her violent response and chastises her for insulting the visitor. As a result, Rolly informs Springer about Welles' larceny. Harper staggers back into the room at that point, clutching his stomach and moaning about something moving inside him. When he collapses and starts frothing at the mouth, Rolly hurries to a back room to grab a medkit, while Welles and Springer go to help him. When they raise Harper's shirt, they notice something moving beneath his stomach's skin. It then immediately tears through and shows a Chestburster.

Rolly, still in the back, hears the sound of gunfire as she searches for a medkit and returns to the front room. She sees that, in his effort to kill the emerging Chestburster, Welles has shot Springer in the neck. Welles continues firing, this time hitting an electrical conduit and shorting out the lights in the storeroom. Rolly rushes to her colleague's rescue. Welles spots the Chestburster again and continues firing.

Welles exits the scene after weighing his options, but Rolly refuses his proposal that she forsake Springer and save herself. Springer dies in her arms despite her efforts. A hardened Rolly decides to lock the storage door and confront the Chestburster, armed with a baseball bat.

It rushes at her from the shadows as she searches through the racks and shelves of materials for the Chestburster. She gets the upper hand and thrashes the small thing to death. Yet, the colony's alarm klaxon interrupts her repetitive pounding of the Chestburster's corpse. Over the klaxon, she can hear screams and shooting. She hears the moans of injured Drones as the clamour grows louder.

Rolly's fate is unclear, but she was most likely slain in the High Lonesome epidemic that followed.
