It's not lost on Vadim that someone is messing with his business. While his own men aren't convinced their troubles are coming from outside parties, Vadim is certain of it. Will his hunt for the truth lead back to Semiyon and Alex?

Watch a Sneak Peek of Episode 5

After the death of one of his men seemed suspicious, Vadim proceeded to do his own investigation, and he found exactly what he thought he would: foul play. That discovery led to a corrupt policeman, who with a little bit of violent persuasion finally gave Vadim a name -- Karel Benes -- the man that Alex and Semiyon paid a visit to in Prague. See what Vadim discovers next in this sneak peek of tonight's all-new episode.
