RESIDENT EVIL: APOCALYPSE begins almost immediately where RESIDENT EVIL ended. The movie gives us a few details surrounding the incidents from the first movie:  Umbrella people opening the Hive which unleashes the zombies infected with the T-virus, Umbrella rounding up their top scientists to evacuate from Raccoon City, what exactly happened to Alice and Matt Addison after they escaped the Hive, etc. Then the fun really begins. The movie jumps around quite a bit as it follows several different characters in several different places scattered throughout the city who don't start meeting up with each other until about half-way through the movie. Jill Valentine and Carlos Olivera (heroes from the Resident Evil video games) have major roles in the film, teaming up with Alice and a few other stragglers as they attempt to escape the city before Umbrella nukes the place to kill off the T-virus before it spreads any further.
