In this fascinating allegorical horror-thriller, a brilliant young neurosurgeon emerges miraculously unharmed from a devastating car crash — only to discover a dark secret about his origins that stretches back to a series of bizarre experiments conducted at the dawn of the Spanish Civil War.

Set in Catalonia, Painless weaves two stories: in one, starting during the Spanish Civil War and running through to the '60s, an asylum attempts to rehabilitate children who feel no pain, by teaching them physical suffering. In the second, in the present time, a brilliant neurosurgeon who needs a bone marrow transplant, discovers this dark past when he searches for his biological parents.

At the dawn of the Spanish civil war, a group of children insensitive to pain is locked in a sanatorium in the heart of the Pyrénées. In the present day, brilliant neurosurgeon David Martel discovers that he has a tumor and starts searching for his biological parents, in order to get the bone marrow transplant necessary for his survival. During his quest, he will exhume terrifying secrets about his origins, reanimate ghosts of his country and confront Berkano, the only fateful survivor of the insensitive children.
