The Alto Knights

The most dangerous enemy is an old friend.

A dark, historically grounded crime drama about the corrosive power of ambition and betrayal between two former allies in the 1950s Mafia underworld.

Two of New York's most notorious organized crime bosses, Frank Costello and Vito Genovese, vie for control of the city's streets. Once the best of friends, petty jealousies and a series of betrayals place them on a deadly collision course that will reshape the Mafia (and America) forever.
