A small sanatorium that can be moved around to let sun in to the two beds inside.
Location of events unknown - France?
A makeshift sanatorium in a field - a small platform covered by a canopy with two beds inside and curtains around it. A nurse stands inside with a soldier (or doctor?). The soldier walks down off the platform and shows how the whole sanatorium can be moved around (must be on wheels or runners underneath). He leaves the platform at a different angle so we can see a patient inside, in bed.
Is it moveable so that the patients can get some sunshine?
