A year in the life of abstract artist Sean Scully, one of the world's wealthiest painters. Little known at home but a superstar abroad, Sean flies around the world to open 15 major museum exhibitions - a journey that also reveals his extraordinary life story. Now, at the age of 73, Scully opens up about his unique experiences spanning 55 years in an often hostile art world. He explains how he built a reputation from nothing - he grew up penniless on the streets of Dublin and London and was often homeless as a child, running with street gangs as a teenager - to turn his striped paintings into the huge success they are today.
