Nikias is a recently freed slave that's come to the big city to find work. He ends up working in a snack stall that occupies one corner of a grand old house. That's where he first spots Kallion, a man about Nikias's age who seems to work at the mansion. The two meet when Kallion is attacked outside the house, and despite some initial misunderstandings, they become friends. But Kallion harbors a dark secret about his cruel former master that prevents him from fully opening up to Nikias.
