Weeks have passed since the events at the end of episode two and business is now thriving in Prague.

With the help of Semiyon's investment, Benes has grown his operation, leaving Vadim concerned and confused. Deciding to take matters into his own hands, Vadim arrives in Prague determined to get answers - by whatever means necessary.

Semiyon's fortunes continue to rise but he and Alex disagree on how to proceed, with Alex wanting to turn the pressure up on Vadim. In the UK, Alex and Rebecca announce their engagement - but it is clear he is distracted. The next morning he receives a shocking call: Semiyon has been arrested in Tel Aviv...

Having almost lost hope that Semiyon will ever let her go, Lyudmilla realises she might have some leverage. Meanwhile, Masha confesses her secret to Katya, and, with Alex away in Israel, Rebecca grows closer to Antonio.
