Paula was born some time in the 2040s. When the aftermath of the 2009 Third Energy Criticality Incident became apparent, she joined her family as part of the Noah's Ark Plan to undo the damages to the timeline. After acquiring a number of dinosaurs, the expedition settled some three million years into their future, where the creatures could be left in peace without harming 21st century history. An unforeseen shutdown of the Habitat Support Facility's timegate left the expedition stranded, and they soon fell victim to the free-roaming dinosaurs.
Paula and several other children survived, and were placed in life-support machines on the orders of her father. Knowing of Paula's future experiences, Morton did enough work on the timegate to guarantee a single, brief activation.
Due to the machines being designed for the psychological development of the dinosaurs, the children were released in their late-teens largely-mute, and distrusted other humans from the temporally-displaced Edward City to the point of armed raids.
Paula met Regina at the Laboratory during a time-travel mission to investigate the disappearance of Edward City, who she and her two surviving comrades tried to kill. They quickly made their way to the Missile Silo, though Regina was forced to save Paula's life when the bridge fell apart beneath her. She was handcuffed in an office while Regina went out to find her comrade, First Lieutenant Dylan Morton, and then taken to their hovercraft, where it was discovered that the other teens had sabotaged it. Interrogated by Dylan, Paula realised she was looking at the younger version of her father.
Escaping from her handcuffs, Paula later caught up with the two in Edward City, where she was forced to betray one of her comrades trying to murder the pair, pushing him off a highway overpass. When Dylan recognised her pendant as having belonged to his deceased sister, he interrogated her as a thief; Paula became emotional and ran away.
After the destruction of the Missile Base, Paula found Dylan washed-up on the riverbank near the Habitat Support Facility. Leading him in, Dylan learnt the truth through an archived holographic message for him recorded by his older self. Ready to escape to the 21st century, Dylan tried to bring Paula with him and Regina. An explosion caused by another of Paula's comrades caused a computer server to fall on top of her, crushing her leg. Dylan ordered Regina to go through the timegate and rescue him and Paula by some other means. Upon Regina's departure, another server collapsed above them, and the facility exploded.
Regina was successful in saving Dylan and Paula in her return, though it soon became clear that there was a new problem. The "Noah's Ark" supercomputer, MTHR, was revealed to be corrupted, and it began capturing various oddities from across time and dumping them in a strange realm known as Hyperspace, threatening the stability of the timeline. Dylan drew out a basic plan to undo this anomaly - Paula would enter the realm and search for the MTHR computer and reboot it. To help her, Dylan searched for a someone to conscript, capturing the moments before their historically-recorded death. The logic behind conscripting a person "destined" to die was that if the person was killed during the mission, it wouldn't cause any adverse changes to the time line.
That someone was Lieutenant Mike Wired, an American pilot serving in 1943, destined to be shot during a dogfight over the ocean. The two worked together in exploring Hyperspace and its many dangers, from a Jet-black Tyrannosaurus to an active volcano. Upon gaining control of the supercomputer, Paula revealed her affections for Mike, and became hesitant in sending him to his death. Upon gaining the courage to do so, she then proceeded to manipulate the past, temporally-displacing the very bullets which would have killed him.
- Paula survived long enough to meet Dylan because she remained in the Habitat Support Facility for the majority of her post-comatose life. That's how she hadn't yet been killed by the dinosaurs.
- At one point during production of Dino Crisis 2, Paula was intended to be Edward Kirk's daughter.
