When Roman architect Lucius is criticized for his outdated thermae designs, he retreats to the local bath to collect his thoughts. All Lucius wants is to recapture the Rome of earlier days, when one could enjoy a relaxing bath without the pressure of merchants and roughhousing patrons. But as he slips deeper into the water, Lucius is caught in the drainage and dragged through the bottom of the bath! He emerges amid a group of strange-looking foreigners with the most peculiar bathhouse customs...over 1,500 years in the future in modern-day Japan! His contemporaries wanted him to modernize, so—borrowing the customs of these mysterious bath-loving people—Lucius opens what quickly becomes the most popular new bathhouse in Rome: Thermae Romae!
