"I'm Simon. I have Asperger's syndrome. I like space, circles and my brother Sam who always looks after me. I dislike feelings, other people, changes and romantic comedies with Hugh Grant." "Simple Simon" is the story of 18 year-old Simon, a boy with Asperger's syndrome whose life is turned upside-down when his brother Sam is dumped by his girlfriend. To make his life work, Simon needs structure. He needs things to follow a certain pattern - with the same schedule, the same meals, the same clothes - week in week out. Sam is the one who's always taken care of Simon. Making him food in the shape of circles and helping him understand humans.
But with Sam depressed over the breakup with his girlfriend everything changes and Simon's world turns into chaos. Wanting things to get back to normal, Simon gives himself one mission - to find Sam a new girlfriend. Unfortunately Simon knows nothing about love and doesn't understand emotions - but he has a scientifically foolproof plan.
