Based on the true story of Augusto and Michaela Odone and their relentless search for a cure for their son Lorenzo's adrenoleukodystrophy (ALD), an extremely rare, incurable, and degenerative brain disorder. Before he turns seven, Lorenzo Odone's childhood is normal. Then strange things begin to happen to him. He has blackouts, memory lapses, and other strange mental phenomena. When he is eventually diagnosed as suffering from ALD, the Odones discover that no-one had been looking into the disease, due to its rarity and the lack of funding. The Odones then begin to educate themselves in the hope of discovering something that can halt the progress of the disease.
