The game begins on the night of Friday 24 July 1998. The Special Tactics and Rescue Service, a police special forces unit consisting of ex-soldiers and scientists, has been assigned into the Arklay Mountains to investigate a series of cannibalistic homicides conducted by an unidentified group of people. Split into two teams, the "Bravo Team", sent out the previous night, has ceased radio contact, forcing the "Alpha Team" to investigate their disappearance on top of completing the mission. Alpha Team identifies Bravo Team's derelict helicopter on the ground and investigates, finding the body of its pilot - Kevin Dooley - but no sign of the others, including its co-pilot, Edward Dewey. Soon into the search, Alpha Team's Joseph Frost is attacked by a pack of mutant dogs ("Cerberuses") and his body torn apart. His comrades, unable to save him, are soon forced to flee from the dogs as well. In the commotion, pilot Brad Vickers takes off, stranding the remaining four members of Alpha Team behind. Chris Redfield, Jill Valentine, Barry Burton, and their leader Captain Albert Wesker, PhD. rush into a large mansion seen from afar.
