What is Derren Brown's "The Push" (aka "Pushed to the Edge") about?

Derren Brown will be back on Channel 4 this month (January 2016) with a brand new special called "The Push" (later changed to "Pushed to the Edge").

The show is about how people comply with authority. The topic sounds like a tribute to Derren's fascination with the Milgram prison experiment. Given the title, I am speculating that volunteers are encouraged by authority figures to harm other humans by either (a) pushing those humans (e.g., onto railroad tracks) or (b) pushing a button that hurts those humans (a la the Milgram experiment). I am guessing the volunteers will comply.

But Derren always finds a way to surprise us. I can't wait to find out what The Push is all about!

Derren was quoted saying: “The world of social compliance is a deeply fascinating one and hopefully we will take the viewer on a journey that will be disturbing and entertaining in equal measure."
