In Párty Hárder, a bunch of friends from the first movie will return. They have already recovered from the previous events and in the summer they will go to the famous Ibiza of the East - to Mácháč, a legendary place full of parties, music and free sex. They promise themselves a lifetime experience and, of course, holiday intercourse. Will they enjoy the summer, or will they fail and only humiliation, involuntary celibacy and the Serbian militia await them?
