Filling in some details from the events right after the original, the sequel begins on a grander scale. All of Raccoon City falls victim to the infection of the T-Virus. Alice (Milla Jovovich) wakes up from experimentation and starts fighting zombies. The film introduces a new set of characters who struggle to survive the Apocalypse. Jill Valentine (Sienna Guillory) is a tough cop who isn't afraid to shoot a zombie in the head as the virus begins to spread. Carlos Olivera (Oded Fehr) is part of a tactical team that ventures into the city to help extract civilians. L.J. (Mike Epps) is a petty crook with custom pistols who is just trying to survive.
As the virus spreads, the military begins to quarantine all the citizens and only evacuate the important members of the Umbrella corporation. Major Cain (Thomas Kretschmann) leads the operation and is tasked with evacuating the scientist Dr. Ashford (Jared Harris) who tasks the remaining survivors with finding his daughter Angie (Sophie Vavasseur).
The movie takes everything that worked in the first one and with a presumably bigger budget expands on the original film. The monster that served as the final villain is multiplied in early scenes as they have bigger monsters and more zombies for Alice to fight. Her abilities increase as well flipping and jumping through the city taking out zombies and fighting the new villain, Nemesis. Another experiment from the Umbrella corp. under the control of Major Cain, Nemesis has a bazooka and a machine gun and is able to dispatch of a whole troop in a matter of seconds. In the end, it is revealed that Dr. Isaacs (Iain Glen) is behind Alice's new strength.
Resident Evil: Apocalypse is a high point in the franchise as it focuses on the action and adds new species to the world. The expanded setting of the city allows for more complex sets and action that lets the characters move around. It still keeps a minor horror element especially as the crew enters a school in search of Angie though retains some of the more idiotic tropes from the genre. Apocalypse is worth a watch for fans of zombies and the video game.
