Environmental activists Thor, Hulk, Black Panther, Captain Anarchy and Batman illegally occupy Mormont Hill. They create a utopian model of society while waging a peaceful struggle against the enemy: the cement industry. Far from any society, these activists invent, create and reclaim a threatened site. A new threat looms when the police announce that they will soon be evicted. Zadvengers offers a poetic and personal vision of the reality of activism in the "Zones to be Defended" (ZADs).
