Nadia Hilker (Spring) and Amber Clayton (St. Vincent) are set as the female leads in TNT’s drama pilot Breed from writer/novelist John Scott Shepherd, director Scott Winant (Fargo) and producer Nicky Weinstock. Breed tells the wild and chilling story of a series of brutal murders in the Pacific Northwest and the mysterious race of creatures who may be committing them. Despite his own mental instability, a gifted detective named Cooper Wells embarks on the case, employing his expertise on serial killers. But when the perpetrators start to reveal barbaric tendencies of an inhuman nature, Wells is forced to enlist the help of a powerful and alluring female assassin to track them.

Hilker will play Ruby, a powerful assassin born of a long line of Eastern European hunters called Avelytes, whose life’s work is to stalk and kill the dangerous creatures that are secretly infiltrating the population. She becomes a volatile but intriguing partner to Detective Cooper Wells as they struggle to protect Tacoma from this unusual and horrific threat. Hilker is repped by Robert Kelly Associates in the UK and attorney Lev Ginsburg. Clayton plays Mandy, Cooper’s girlfriend who followed him from New York to Tacoma after he got fired from the FBI. Their intensely sexual, playful and happy relationship anchors Cooper’s life, but could become threatened by the dangerous creatures targeting them, and by the secrets she’s keeping.
