Three Vietnam vets have become so conditioned to violence that they have developed psychotic tendencies. They kidnap people, brutalize them, then turn them loose and hunt them like animals. However the father of one of their earlier victims is plotting a vicious revenge against them.
Unfortunately the movie Open Season is not yet available on HBO Max.
