The work of Leiden professor Bastiaans on dealing with the trauma of war victims attracts the attention of filmmaker Louis van Gasteren. He decides to make a film about the psychotherapeutic treatment with LSD of a former concentration camp prisoner in the clinic of Bastiaans. Patient Joop is arrested in September 1941 and begins a long hellish journey through various camps, until he is liberated by the Russians. When he returns to his wife, he has become a completely different man. Joop suffers from nightmares and is incapable of normal human contact. With two cameras, Van Gasteren records approximately six and a half hours of the first treatment that Joop undergoes with Bastiaans (four more will follow later). Special attention is paid to details: Joop's hands, the sweat on his forehead, a tear running slowly down his cheek. Van Gasteren reduces the recordings to more than an hour.
