The Whistlers Overview

Cristi (Vlad Ivanov), a corrupt Romanian cop, is on the take. His boss, Magda (Rodica Lazar) is onto him and has installed cameras in his apartment to spy on him.

Knowing this, Cristi agrees when a gangster wants to send him to the Canary Islands to learn an ancient indigenous language that uses whistling in place of words, because the untrained don't realize it's a form of communication. This will enable Cristi to communicate with others trained in the language to help spring a drug lord from jail.
