Inspired by true events, Olympic swimmer Harry Melchior defects from East Germany in the 1960s and hatches a daring plot to help his sister and others flee East Berlin through a 145-yard underground tunnel.
The film builds tension through craft: you hear shovels, see dirt, water and cramped supports, and the danger comes from everyday life at the border. The tone is serious and tight, carried by a team that holds together. Because it rests on real events, the sense of risk never lets up.
Good for you if you like escape stories from East Germany based on true events that draw you into the tension with a calm, precise build.
