The Whistlers [DVD] [2020]

Not everything is as it seems for Cristi, a police inspector in Bucharest who plays both sides of the law. Embarking with the beautiful Gilda on a high-stakes heist, both will have to navigate the twists and turns of treachery and deception. A secret whistling language spoken on the Spanish island of La Gomera might just be what they need to pull it off.
