In the 1960s, Dr. James Marcus discovers the "Ur-Virus" while researching Paleozoic microbial fossils for a Swiss university. After being caught in a scandal involving falsified test results, he is forced to continue his virus research without the university's help. His friend, Ozwald E. Spencer has the Spencer Foundation fund Marcus' research at his castle homestead. Working with Edward Ashford over several years, he succeeds in creating new life by exposing the Ur-Virus to the ancient Archean atmosphere. Showing Spencer the findings, the three found the Umbrella Corporation.
The Ecliptic Express
Out in the Arklay Mountains in 1998, a young couple is forced to stop their car in the night. While the driver goes out on a walk to the nearest petrol station to fill up the tank, his date is left in the car waiting for two hours, breaching curfew. She contemplates how terrible their night out has gone. Seeing her date shamble back, she gets out and insists he just drive her home instead; he is revealed to be a zombie and rips his teeth into her jugular, splashing blood all over the car windscreen.
Later in the night, the S.T.A.R.S. Bravo Team fly their police helicopter over the Arklay Mountains to investigate the recent murders. Since the couple's murder, a heavy storm has arrived. A sudden engine problem forces the helicopter into an emergency landing. Edward Dewey calls Rebecca Chambers over to him to check his wounds; Rebecca is annoyed by his referring to her as "Medic", despite the greater roles of "Rear Security". Moving to investigate a call to help, she finds Edward has taken advantage of the landing for a hazing.
Captain Marini orders the team out of the helicopter and briefs them on the situation. They are in Area Romeo, northeast of an estate located in the vicinity of the killings. Rather than wait for the weather to clear up in order to fix the helicopter, Marini has the team start their search of the area right away. Marini notices the helicopter's radio is down, so orders Dooley to wait for the inevitable rescue helicopter to look for them, expecting the team to return in two hours.
At 23:02 the team find an overturned prison transport vehicle alongside the corpses of its military police drivers. While the prisoner can't be found, the team recovers a document identifying him as Billy Coen, a former marine on death row for war crimes. Captain Marini gives the team new orders to go look for Billy instead. Rebecca is paired up with Richard Aiken, but they get split up in the notoriously-thick forest. Rebecca notices a train stopped in the woods; suspicious, she checks it out. Shouting out into the train for anyone, Rebecca enters it believing it to be empty. Inside she is confronted by a Zombie with its neck torn out. She tries to escape, and its head is blown off by Billy Coen. She tries to arrest him, but the situation renders it impossible. He saves her again from a zombie behind her. Rebecca suggests they get out of the train, but Billy points out they are already moving. The two are soon faced by leeches.
Meanwhile, William Birkin and Albert Wesker watch through security footage of a nearby laboratory, watching zombies shamble from screen to screen. When a strange man appears, Birkin jokes it is the ghost of Dr. Marcus. Wesker does not feel like joking and makes it very clear this man must have a link to the estate, but since they plan to blow it up along with Dr. Marcus' "private zoo", it doesn't really matter. Watching more of the feed, Birkin deduces that the leeches Marcus' was experimenting with when he was assassinated ten years earlier are the genesis of this new man. The reason it took ten years, he concludes, is due to how hard it was for the leeches to regenerate his brain after being shot in the head.
