Le Vent de la liberté

1979, East Germany at the height of the Cold War. Two ordinary families yearning for freedom secretly form a great escape plan to the get across to the West: with courage and ingenuity as their main weapons, they construct a hot-air balloon out of small pieces of material so that their eight family-members can fly over the Berlin Wall. But an initial failure puts their entire plan in jeopardy, setting off a dangerous race against time for a second attempt, with the East German State Police now hot on their heels... An incredible and gripping true story of resistance. (Berlinale)
