Louis Theroux: Extreme Love

Louis visits one of the best schools in America for autism. He meets the students and their families to get a glimpse of what life is like for them and to experience the pleasures and the strains of one of the most extraordinary kinds of relationship.

Louis travels to Phoenix, Arizona - the capital of dementia care. He spends time at Beatitudes, a residential institution, and also with those looking after loved ones at home to try to understand the struggle of living in a world of encroaching shadows - and of keeping relationships alive in circumstances that can be among the strangest and most challenging imaginable.
