В возрасте восьми лет Пак Джу Хён был усыновлен итальянской семьей и уехал жить в Италию. Позже он присоединяется к мафии, и его усыновляет Дон Фабио, глава мафиозной семьи Кассано. Сменив имя на Винченцо Кассано, он становится итальянским юристом, консильером мафии и правой рукой дона Фабио. После смерти Фабио Паоло, биологический сын Фабио и новый лидер семьи Кассано, пытается убить Винченцо.
   Винченцо едет в Сеул и намеревается вернуть 1,5 тонны золота, которое он помог найти недавно умершему китайскому магнату, тайно спрятавшему его в подвале Кымга Плаза. Однако компания по недвижимости, входящая в состав Babel Group, незаконно стала владельцем здания, и Винченцо должен использовать свои навыки, чтобы вернуть здание и своё состояние.
   Среди необычных арендаторов Geumga Plaza — юридическая фирма Jipuragi, которой управляет Хон Ю Чан. Сначала Винченцо вступает в конфликт с дочерью Хон Ю Чана - Хон Ча Ён, адвокатом конкурирующей фирмы, но после смерти отца она берёт на себя практику и объединяет усилия с Винченцо и другими арендаторами для борьбы с Babel Group...
