Please answer the following question: Question: Where is Matt Denant sentenced to three years? If there is no answer, please output "Insufficient information to provide an answer.". Movie title: Escape Context: Famous German stage actress Emmy Ritter (Alla Nazimova) is held in a Nazi concentration camp. She is scheduled to be executed soon, but the sympathetic camp doctor, Ditten (Philip Dorn), has been a fan since childhood and offers to deliver a letter from her to her children...afterwards. Emmy's son Mark Preysing (Robert Taylor), an American citizen, travels to Germany in search of his mother, but nobody, not even frightened old family friends, want anything to do with him. A German official tells Mark that she has been arrested and advises him to return to the United States. The postmark of a returned letter guides Mark to the region where she is being held. There, he meets by chance Countess Ruby von Treck (Norma Shearer), an American-born widow, but she also does not want to become involved, at least at first. Then, she asks her lover, General Kurt von Kolb (Conrad Veidt), about Emmy and learns that she has been judged a traitor in a secret trial and sentenced to death. At a concert, Mark encounters Doctor Ditten, who takes the opportunity to deliver Emmy's letter. Then, Ditten drugs Emmy into a coma, making it appear as if she has died. He tells Mark what he has done. Mark sends longtime family servant Fritz Keller (Felix Bressart) to collect the coffin, but the American's nervousness raises the suspicion of the political police and he is brought to the camp for questioning. Fortunately, he is allowed to take his mother's body away. When the road is blocked by snow, Mark is forced to find heat and shelter for his mother at the house of the countess. The next day, he meets von Kolb, who is jealous of the younger man. Later, when Mark and a disguised Emmy leave for the airport, von Kolb guesses what is happening (from Mark's earlier lack of reaction to the news of his mother's "death") and confronts the countess. She begs him not to interfere, but he is implacable. Knowing about his health problems, she taunts him with her love of Mark, which provokes him into having a heart attack, giving her new friends...
