Derren Brown - Trick or Treat
Kitten
S2 E2:
Derren demonstrates the power of negative suggestion by taking 19-year-old Lauren on an emotional rollercoaster to see if, having been told not to, she can resist killing a kitten, which is in a metal box wired up to the mains electricity. Along the way, Derren makes a seasoned circus performer fall off the high-wire and a group of schoolchildren succumb to temptation while being observed on hidden cameras.
