Loosely based on real events that took place during Matteo Messina Denaro's thirty years on the run. A disgraced politician is gifted a second chance when secret services involve him in an operation to root out an elusive Mafia boss. Using his personal connection as the Boss' godfather, his task is to get him to reveal his hiding place in their secret letters.
Unfortunately the movie Sicilian Letters is not yet available on HBO Max.
