Valley of the Wolves (2003)

Original title: Kurtlar Vadisi

One of Turkey's most iconic and influential dramas, Valley of the Wolves follows Polat Alemdar, an undercover agent who infiltrates Istanbul's most dangerous crime organisation after years of preparation. Combining organised crime, covert operations and sharp political commentary, the series fearlessly tackles Turkey's shadowy relationship between the state, the mafia and power — and became a cultural phenomenon that spawned multiple films and spin-offs.
