The new pan-European original drama follows the story of morally ambiguous people as well as complex relationships in an opulent world of the ultra-rich. The life of a newly-married, Midwesterner woman, Georgina (Stile) is blown apart after a year of marriage.

Georgina's art collector husband Clios is killed aboard the exploded yacht of a Russian arms dealer and oligarch. Georgina believes there is more to the tragedy and tries to find out what really happened.

Georgina found some dark truths about her husband's dealings and starts to know the person she married. She immerses in a world of criminality, lies and double-dealing.

Georgina in her school days was an A-plus student, a fine-art scholar in the United States. Now she needs to adapt, survive and thrive in a dangerous reality to protect the family and its fortune, including the legendary Côte d'Azur mansion of the Clioses.

Lester plays as the art dealer and Georgina's friend Robert Carver. The Sky series also stars Lena Olin as Clios' beautiful ex-wife Irina, Phil Davis as art investigator Jukes, Roxanne Duran as Adriana and Leonidas as the other son of Clios, Christos.

The emotionally-driven drama on Sky is based on the idea of Paul McGuinness who was the former manager of U2. It is created by Oscar-winning writer and director Neil Jordan whose credits include the 2011 "The Borgias." Co-writing with Jordan is Booker Prize-winning author John Banville ("The Sea").

Producing the project are Primo Productions as well as Kris Thykier and Liza Marshall's Archery Pictures. Executive producing are Thykier, McGuinness, Marshall and Jordan. Foz Allan is the producer while Sky Vision takes care of the worldwide distribution, Deadline reported.

Filming will start on the 10-part thriller set against the sun-drenched South of France. The drama will be available next year in the United Kingdom, Austria, Germany, Italy and Ireland.
