Langer was the supervisor in charge of Receiving Station #6-D in Silver Leaf, Nebraska. She was on duty on October 3, 2004 when Weyland Industries Satellite PS-12 detected a heat bloom in the Yautja pyramid beneath the ice on Bouvet Island, thereby initiating a series of events that led to Charles Bishop Weyland accompanying an expedition to the island to investigate.
- Langer actress Liz May Brice has a distinctive deep, husky voice; it appears her dialogue in Alien vs. Predator was dubbed over by another actress with a higher-pitched, softer tone.
- In the novelization of the film, Langer is said to be a man, but she is female in the film.
