The Conversation (2018)

Sam, an ex-undercover operative, agrees to meet his handler to negotiate his exit from an elite squad of covert killers, only to be double-crossed and forced to fight for his life against people he once considered friends in the sprawling streets of Barcelona. Left for dead, Sam gets it together, and with nothing to lose, he heads back to the people that taught him how to be an assassin for a deadly version of the game, 'show and tell.'
