Undercover (2011)

Just an ordinary boy from the Sofia suburbs becomes the first bulgarian undercover cop. Forced by his father when he was young to lie and cheat, Martin becomes the perfect liar. That skill, and also the hatred of the 'underworld' makes him the perfect match for a dangerous mission - to infiltrate the crime organisation of a rich and powerful businessman. While infiltrating and living in fear of being uncovered, Martin falls in love with the most inappropriate woman - Djaro's girlfriend, Suni. Just when he gains the trust of the mobsters, it appears that the real enemy is in the police. Martin is alone against all, facing difficult decisions.
