Hannah was a Weyland-Yutani Corporation employee and a crewmember aboard the comet plasma harvesting ship USCSS November. She was serving aboard the vessel when it was infiltrated by a Xenomorph, the incident ultimately leading to the destruction of the ship and the death of its crew.
Although Hannah and her partner Alec escaped the November before its destruction, they were both locked inside their escape pod with several Facehuggers, ultimately falling prey to the creatures and presumably dying when the Chestbursters they implanted emerged.
