The video starts off with a guy teaching a class, and he brings out a projector. It shows a bunch of guys in animal masks being treated badly by humans, and then eventually the animals take over and form their own society based on fairness.
Eventually there comes tenants to treat other animals and it gets twisted to be more beneficial to a certain animal over another. At the end these two guys who rigged the system take off their masks and reveal they’ve been “humans” this whole time.
It’s a metal song.
