The game features branching paths that allow the player to determine how the story will unfold and whom they will meet along the way. The game takes place after the missile explosion that wiped out the contaminated Raccoon City. Not long after this incident, a helicopter crashes on the outskirts of Umbrella Corporation's private township, located on Sheena Island. The pilot escapes the burning wreckage only to find himself fighting a battle against the living dead, with no memory of his identity or his reasons for being there. During his quest, he comes across a man named Andy Holland, who knows him as Vincent Goldman, the man said to be responsible for the outbreak of T-virus in the island. Due to his amnesia, he assumes this as a fact. Moments after he gets out of the city, "Vincent" comes across Umbrella's facility, where he meets Lott and Lily Klein, two siblings whose parents used to work for Umbrella. They misjudge him because they were made to believe that Umbrella stands for the common good of all people. The two kids run away from him during their encounter, as "Vincent" follows the children outside the facility, through the canal system, and eventually to their house. He finds Lily in the house and learns from her that Lott has gone to a nearby factory alone to find a way off the island. Upon learning this, "Vincent" tells Lily to stay and take refuge until he comes back with Lott. He finds his way to the place and, after encountering many monsters, successfully infiltrates the Umbrella research facility just in time to save Lott from a Hunter. "Vincent" then learns from Lott that he is, in fact, Ark Thompson, that he was sent to Sheena Island by Leon S. Kennedy, and that Lott knew who Vincent Goldman really was. Due to his knowledge, Vincent later became a vehement enemy of Ark. However, upon this realization, the facility suddenly activates a self-destruct system that will obliterate the island within 10 minutes. Lott tells Ark that within the facility, there is a railway station that runs underground. Ark tells Lott to go ahead to the station first and regroup there. However, along his way to the station, Ark encounters the real Vincent and the Hypnos T-type Tyrant. Much to his surprise, the Umbrella executive is killed by the new bio-organic weapon, which then turns its attention to Ark, who manages to hold it off long enough to make a getaway.
