Every human brain is a high-performance machine. But some people are real “Superbrains”. Like Michael und Matthew Youlden. The twins speak more than 20 languages fluently. Sebastian und Philipp Weyer are also twins. They solve the Rubik’s Cube in seconds. Elisabeth Sulsers‘life is colourful: When listening to music, she sees the G in blue and C in red. Finally, there’s Derek Amato who became a musical genius after an accident. “The Human Limits II” portrays these extraordinary personalities.
