Instantly attracted to each other they make plans to move in together. Benedict likes sitting around and smoking. He is a painter hoping for a lucky break. As Adam runs by Benedict sketches him. When he persuades Adam to sit for a painting, the result is a picture that leaves its mark on all of them for the rest of their lives.
