Thursday 23 July: Umbrella's private train, the Ecliptic Express, is attacked shortly after 8 PM by leeches while transporting the second investigation team to the executive training school. The passengers and crew are infected, and the train comes to a halt. Nearby, 2LT Coen escapes from captivity when the MPs are killed by leeches, and takes shelter in the train. Meanwhile, the first investigation team is set upon by leeches at the training school and, attacked by Cerberuses at the front door, are forced to travel to an abandoned factory via a cable car. Drs. Birkin and Wesker order the USS Delta Team to commandeer the train.
Two hours after the initial attack on the Ecliptic Express, S.T.A.R.S. Bravo Team crash lands in Raccoon Forest. While searching the area, Rebecca Chambers and later Edward Dewey get on board the Ecliptic Express while Delta Team restarts it. RPD helicopter pilot Kevin Dooley is killed in his cockpit, and the other Bravo Team members escape into the Spencer Mansion. During the journey, Dewey turns into a Zombie, and Delta Team is infected by leeches, forcing Chambers and Coen to work together to prevent a train crash. They arrive at the executive training school, itself infested with Zombies and escaped B.O.W.s.
Friday 24 July: In the early hours, Chambers and Coen search through the training school and make their way to Dr. James Marcus' derelict underground laboratory. Coen is attacked by an Eliminator and falls into an underwater river, sending him to the water treatment plant. In the meantime, the survivors of the second investigation team are attacked by more leeches when Queen Leech attacks the water treatment plant. Chambers arrives at the factory to find Enrico Marini is also investigating the area, but she continues on her own and, after fighting the Proto-Tyrant, journeys to the water treatment plant where she rescues Coen. During this, Dr. Wesker heads out through the factory, intent on searching the executive training school while Dr. Birkin makes preparations to destroy the entire complex; he fights the Proto-Tyrant as well during his search. The Tyrant heads to the water treatment plant, where it is finally killed by Chambers and Coen, who soon run into the Queen Leech itself and fight it. During their fight, Dr. Birkin activates the self-destruct system as Dr. Wesker fights one of Col. Sergei Vladimir's custom-made "Ivan" T-103 bodyguards in the training school, but the only death is Queen Leech itself, which is killed in the explosion. Chambers and Coen part ways, and she heads over to the Spencer Mansion to search for Bravo Team.
In the evening, Chambers is discovered sleeping in the dormitory by Richard Aiken. They start searching through the complex for Captain Marini, but fail. During their search, they spot Col. Vladimir and his Ivans carrying the T-011 test subject out of the mansion. While exploring the second level of the mansion, Aiken is bitten by the Yawn and poisoned. Meanwhile, the S.T.A.R.S. Alpha Team investigates the Bravo Team crash site for any clues as to their whereabouts. When they are attacked by Cerberuses, losing Joseph Frost, they locate the house and go inside for safety.

Wesker has forced Burton to destroy incriminating material on his behalf on the threat of his family's lives. Aiken's fate is uncertain.
Saturday 25 July: During the early hours, Cpt. Marini is shot by Cpt. Wesker, having discovered during his investigation that Umbrella planted a mole within S.T.A.R.S., but failed to identify them. Entering the lab, Cpt. Wesker infects himself with a prototype t-Virus strain, hoping to fake his death and hand over the lab's bio-weapons data to the Organisation rather than to Umbrella as was originally the plan. When the other four arrive in the lab, he releases the T-002 Tyrant and is impaled on its claws. T-002 chases the S.T.A.RS. members to the helipad, where it is killed by a rocket launcher, and they escape on the Alpha Team helicopter back to Raccoon City. Meanwhile, Cpt. Wesker discovers the bio-weapons computer data has already been copied and wiped by Col. Vladimir. With no time to gather live samples as the facility begins to self-destruct, Cpt. Wesker uses his new abilities to race through to the mansion, where he fights Lisa Trevor. After Trevor is subdued, Cpt. Wesker escapes the explosion thanks to his enhanced speed.

Soon after, Kendo kills his infected daughter, Emma, having already killed his infected wife. Kennedy is shot by Annette Birkin when he and Wong confront her, and Wong later suffers an injury which forces Kennedy to search for her. Both groups of survivors and Annette travel at their own times to NEST.

During one of these events, William confronts the person returning from the lab and seriously injures Annette prior to a fight with Kennedy; Annette soon after dies from internal hemorrhaging. Redfield and Sherry escape onto a train following another encounter with William, while Kennedy and Wong turn on one another when her identity as a spy is revealed.

Valentine is treated, and the two head out looking for a means out of the city. During their separate travels to the P-12A Plant, both become aware that the US military now intends to fire a missile into the city to contain the outbreak. Sgt. Zinoviev takes a helicopter from the P-12A plant to allow his escape, but when the US military abandons its air blockade, Barry Burton takes the opportunity to fly into the city, searching for Valentine on the radio. While she fights and kills the Nemesis-T Type, Cpl. Oliveira directs Burton to the scrap yard near the plant, and he picks the two up as the city is destroyed by an experimental thermobaric bomb.
Elsewhere in the city, a group of survivors led by Dr. George Hamilton travel to Raccoon University in search of Dr. Jenkins, after Dr. Hamilton found a letter from him at a refugee centre. Their search for his own vaccine, Daylight, interferes with a U.B.C.S. operation to take down the rogue Umbrella researcher Dr. Greg Mueller and his Tyrant, Thanatos. The team is ultimately successful in taking down Thanatos, while Sgt. Zinoviev is successful in assassinating Dr. Mueller. They escape in a Raccoon Fire Department helicopter with a sample of Daylight as the city explodes.
A third group of survivors led by David King finds themselves at Umbrella's R&D Center, where Dr. Linda Baldwin is searching for a prototype treatment to the t-Virus she was working on before the outbreak. Another survivor, Dr. Carter, awakens Tyrant R to take down the escaped Hunter Rs, but the Tyrant turns on him to prevent him using a remote for the bomb in its chest. The survivors find Dr. Baldwin in a water treatment plant, but she is washed away to a storm drain near the Apple Inn. She is then shot in the leg by U.B.C.S. member Arnold who has orders to kill Captain Rodriguez, a USS operator who is waiting for Dr. Baldwin to return so they could escape the city together. Whether this group escapes with Cpt. Rodriguez or gets out of the city is unknown.
