Poor Herschell, he just got back from serving in Vietnam when he hooks up with the wrong crowd, gets pressured into smoking a joint and is immediately hooked! This leads him into being duped into eating experimental turkey meat by two scientists who offer to pay him in Marijuana. Unfortunately one of the side effects from eating the turkey is Herschell becomes a terrifying half man half turkey chimera with an insatiable hunger for the blood of marijuana addicts!
So remember kids, just say no to turkey or something....
