I figured it would probably be best to post some resources for getting into the series since it's relatively new and not well known.
Milgram is about 10 prisoners held within a facility. Using a device, the warden extracts their memories in the form of music videos. The twist: they're all murderers.
You, the viewer, are tasked with analyzing the music videos for methods/motives to determine whether a prisoner's murder is justified or not. You can vote on the website or via the app once every 24 hours.
There is also an app that periodically posts little snippets of character interactions, as well as drama CDs for each character album released. The third prisoner's music video drops on 9/30.
