An Italian mafia lawyer, who is the adopted son of a mafia boss, returns to South Korea and gives a corrupt conglomerate a taste of its own medicine with a side of justice.

The described television series is "Vincenzo (Review)." This popular South Korean drama centers on Vincenzo Cassano, a Korean-Italian lawyer and consigliere to a mafia family, who returns to his birth country after a power struggle within his adoptive Italian crime family. His initial goal is to retrieve a large sum of gold hidden beneath Geumga Plaza in Seoul.

However, Vincenzo soon finds himself entangled in a battle against the corrupt Babel Group, a powerful conglomerate that uses illegal and unethical means to achieve its goals. Partnering with the tenacious lawyer Hong Cha-young, he employs his dark, mafia-honed tactics to dismantle Babel Group and deliver a unique brand of justice to those who exploit the innocent. The series is known for its blend of dark comedy, thrilling action, and poignant moments, often highlighting the idea that "only evil can punish evil."

"Vincenzo" garnered significant international attention upon its release in 2021, becoming a global hit on Netflix. The drama features a stellar cast, with Song Joong-ki in the titular role, praised for his portrayal of the charismatic anti-hero. Interestingly, while many scenes depict Italy, the production team utilized computer graphics to recreate Italian settings due to the COVID-19 pandemic, filming entirely in South Korea. The show's compelling narrative, strong performances, and unique approach to justice made it a memorable addition to the K-drama landscape.
