Castro's Spies: into the lives of the Wasp Network
★★★★☆
(PG) is a documentary by Ollie Aslin and Gary Lennon about the so-called ‘Wasp Network’ — a group of Cuban operatives sent to the US in the wake of the Fidel Castro’s Cuban revolution, with a mission to infiltrate the CIA-backed groups of Cuban exiles who, having been thrown out of Cuba for being pro-American, were plotting to overthrow Castro’s rule.
