Formosus Petrus, through family misfortune, became a young slave in a Roman laundry. Unaware of his gifts, he has no hope or protection from the greedy citizens and slaves who seek him out for sexual satisfaction. He resigns himself to his miserable fate with no money and no chance to earn his freedom. His luck changes when Longinus Megas, an enormously endowed Thracian slave, arrives at the laundry. He sees value in the handsome young slave. The much stronger Longinus defends and promotes Formosus, who easily accommodates the massive needs of his heroic protector. Many Roman citizens will part with money for a chance to be with these two extraordinary men. Together they hatch a plan to gain their freedom.
