In the aftermath of World War II, a former circus entertainer who was spared from the gas chamber becomes the ringleader at an asylum for Holocaust survivors.

This movie follows the story of Adam Stein, a charismatic patient at a mental institution for Holocaust survivors in Israel, 1961. He reads minds and confounds his doctors, lead by Nathan Gross. Before the war, in Berlin, Adam was an entertainer - cabaret impresario, circus owner, magician, musician - loved by audiences and Nazis alike until he finds himself in a concentration camp, confronted by Commandant Klein. Adam survives the camp by becoming the Commandant's "dog", entertaining him while his wife and daughter are sent off to die. Years later, we find him at the Institute. One day, Adam smells something, hears a sound. "Who brought a dog in here?" he asks Gross. Gross denies there is a dog, but Adam finds him, a young boy raised in a basement on a chain. Adam and the boy see and recognize each other as dogs, and their journey begins. This movie is the story of a man who once was a dog who meets a dog who once was a boy.

In Berlin, the Jewish Adam Stein is a successful artist that works with his wife and two daughters in a cabaret. During the World War II, Adam and his family are sent to a concentration camp and the cruel Commandant Klein, who was his fan, assigns Adam to become his "dog" to entertain him. Adam has to live like a dog with another dog, Rex, while tries to convince Klein to save his wife and his little daughter that are sent to the ovens. After the war, Adam is sent to a mental institution in Israel for Survivors of the Holocaust under the care of the psychiatric Dr. Nathan Gross and becomes a leader among the patients. He also has a mistress, the nurse Gina Grey, who loves kinky sex. One day, Adam smells a dog in the institute, which is forbidden, and he finds a boy that was raised chained in a basement and behaves like a dog. Adam recalls his period as a dog in the concentration camp and gets close to the dog-like boy and their journey together begins.—Claudio Carvalho, Rio de Janeiro, Brazil
