For fans of British crime series who have been looking for something a little different, it's time to turn to Sweden. The international co-production 100 Code follows a Swedish detective, Mikael Eklund (the late Michael Nyqvist) who is paired with an NYPD cop named Tommy Conley (Dominic Monaghan) to investigate a serial killer in Stockholm. There seems to be a connection between this killer and one who recently terrorized New York, as he has a very particular MO (of killing blonde, blue-eyed women in fields of flowers).

The 12-episodes limited series comes from Bobby Moresco (Crash, Million Dollar Baby), and embraces not only some familiar crime show dynamics (the two hardboiled detectives hate each other, of course, and battle their own demons), but also takes place across an international stage as the scope of the crimes widens. Check out our exclusive promo and poster below:

100 Code premieres Tuesday May 29 at 10/9c on WGN America. Here's the official synopsis:

“100 Code” is a tense crime thriller, following the hunt for a serial killer who targets young, blonde and blue-eyed women, found dead in fields of flowers. Through a special arrangement with the NYPD, Detective Tommy Conley (Monaghan) is permitted to observe and advise the Stockholm PD, as he suspects a connection between a series of murders in New York and a death in Sweden.  Upon arrival in Stockholm, he is paired with Mikael Eklund (Nyqvist), a Swedish cop with an aversion to American culture. Both detectives despise each other, but the two are quickly forced to resolve their differences as the mysterious killings continue.  With the vicious killer still at large, Conley and Eklund embark on a hunt that leads the duo down a path of no return.
