Colette tells the story of 90-year-old Colette Marin-Catherine, one of the last surviving members of the French Resistance, who confronts her past by visiting the Nazi concentration camp in Germany where her brother, Jean-Pierre, was killed. She always refused to set foot in Germany. This changes when a young history student named Lucie enters Colette’s life as part of her research into the camp where Jean-Pierre died. The film follows Colette as she travels with Lucie to what remains of the forced labor camp near Nordhausen, Germany, in a journey of discovery that reopens old wounds and lessons of the past.
