Director Walter Heynowski’s short documentary, filmed in Totalvision (CinemaScope), is a call for East Germans to donate blood for the (North) Vietnamese people. The film’s title is a reference to how much blood a person was allowed to donate. The intercut footage of blood donors and the Vietnam war is set to choral music by Paul Dessau.

The short is one of the series of films that Walter Heynowski and his colleague Gerhard Scheumann shot during the Vietnam war, which were shown in cinemas and on television in the GDR.
