However, his wife's departure seemed to help him get rid of the last bit of worry, and with the help of his friends, he sneaked out of the nursing home. Guttman carried a letter written by a friend, which recorded the things he needed to pay attention to along the way and the biggest purpose of this trip. After several twists and turns, he finally found an old man named Rudy Kland. When he was young, the other party was a German soldier who participated in World War II.
