Lucius Modestus, an ancient Roman architect, is looking for work since he is having difficulty coming up with fresh ideas. His pals attempt taking him to a bathhouse to calm him as his manner and personality deteriorate. Lucius drops his head in the water, unable to relax in the frantic and crowded bath. He discovers a secret tunnel that leads to a modern-day Japanese bathhouse, providing him with the inspiration he needs to create something fresh. Lucius, armed with what appears to be knowledge far ahead of his time, does his best to duplicate his discoveries, which are typically of lesser quality owing to his circumstances. However, simple creativity may be sufficient to attract the folks' attention.
