It will be something like spin-off, restart. All events in the POSTAL series "Postal2, AW, PL, Postal 3" are ignored. Protagonist is still the same "The Dude" who lives in city of "Paradise" and deals with household affairs. Looks like it's same thing, but with slight differences: "The Dude" now teenager.
