Sam, a resident of the "real world," is transported to the fictional world of Greene in order to prevent Biohazard Harry (simply referred to as "Bio-Haz" in the game) from continuing to pollute Greene, a world of seven nations.

Sam's adventures range from collecting debut records to helping to expose a corrupt politician.
