Hunter S. Thompson was an author trapped in the body of a rock star. His drug-fuelled adventures were legendary and became the basis of one of the classics of 20th century literature. Thompson's constant questioning of authority and wild antics made him a hero for a generation of rebels across the globe. But in the end it wasn't enough. A lifetime of alcohol and drug abuse was taking their toll. At 67, with a broken leg, two hip operations and in chronic pain Thompson could no longer live up to the legend he'd created. Final 24 charts the life of this troubled genius and uncovers why a bullet to the head was the only way out.
