The story of artist Salvador Dali and Vision of Hell, a painting that was hidden under a nun's bed for 30 years yet had a profound effect on the life and work of Dali. Vision of Hell was a painting of one of the religious visions seen by three children in Fatima, Portugal in 1917. Dali was commissioned to work on this painting during a period in his life when he was deeply concerned about his mortality, so much so that he obsessed about death and openly mused about hopes for immortality. He began to study the possibility of being cloned and even considered being frozen in hopes of being resurrected decades later as a means of achieving some form of immortality. As he worked on Vision of Hell, the master found himself being pulled back to his religious roots. He returned to the Catholic Church, keeping it secret from those in his inner circle, and introduced substantially more religious themes into his work, producing four times more religious work after painting Vision of Hell. Yet the master hid his new found devotion from many close to him for fear of losing his intellectual and anti-church reputation. As much as anything, it is about the master's dreams of everlasting life and his attempts to achieve it in any way possible. It is an untold story that significantly changes the biography of Salvador Dali.—Paul Perry/Director

As Salvador Dali aged, the great artist found himself trapped between the atheistic beliefs of his father and the Roman Catholic beliefs of his late mother. He admitted to feeling spiritually trapped. In 1959 that all changed. A Catholic organization in New Jersey hired him to paint The Vision of Hell, one of the visions seen by the child seers at Fatima, Portugal. The painting was suppose to be a work for hire and nothing more. But when Dali began to study the visions and then eventually visited Fatima himself, he converted to Catholicism and his art work became more religious. Yet he kept the conversion secret from many of his friends, making this Dali's Greatest Secret.
