Eighty-year-old doctor Co regularly holds office hours in a walk-in facility for homeless and uninsured people. In addition, he cycles across Amsterdam, looking for people he can give medical help. He descends into a shadow world of vacant garages and squatted office blocks, like the Vluchtgarage. Here, at ungodly hours, he helps rejected asylum seekers who are stuck and cannot go to regular doctors. What drives this aged ‘street doctor’ to be up and about at night to help these people?
