Cuba Crossing (1980) on Netflix

Plot summary

Hud is a Bay of Pigs survivor who wants Fidel Castro dead. Years afterward, Mr Rossellini offers him the means to act: the man blames Castro for the gambling business he lost when he had to leave Cuba. A mysterious figure, Mr. Bell, puts up the money for a mission to the island. Hud intends to land a father and son, both sharpshooters, and have them kill Castro while he is staying at a hotel on Isla de Pinos. To get the pair ashore, Hud turns to Tony, who owns a bar and captains a boat.
