The Nature of Things - Season 52

Fightland follows a disgraced, formerly incarcerated boxing champion who returns to London to seek vengeance against the crime family he thinks betrayed him. With edge-of-seat action and populated by dangerous characters, this is a world of money and power never seen before.

On the night Duke Kilroy becomes world heavyweight champion, a vicious assault leaves his brother, Calvin, dead, causing Duke to snap and results in him spending eight years in a U.S. prison. Upon his release, and after having made a sinister discovery, Duke returns home seeking vengeance against the man he believes set him up -- the criminal kingpin and former promoter, Kingsley Marshall. But Kingsley has vanished, leaving his children and wife, Joy, who happens to be the love of Duke's life, to pick up the pieces.

Working with a cartel desperate to control London's drug market, Duke begins a high-risk game of infiltrating Kingsley's empire to destroy it from within and smoke out his enemy. But amidst a volatile criminal landscape, and competing influences threatening to pull him off course, Duke will need to channel everything that made him a champion fighter into his bloody pursuit to win the ultimate victory - revenge for his brother.
