Tracy Spiridakos will lead her first new series since departing "Chicago P.D.", with USA Network's "Anna Pigeon" set to premiere in early August. The show marks a significant career step for the actress, who spent seven seasons on the NBC procedural as Detective Hailey Upton before leaving in Season 11, and it comes as USA Network continues expanding its slate of original scripted dramas.

Based on Nevada Barr's mystery novel series, "Anna Pigeon" sees Spiridakos play a former city dweller who reinvents her life after the death of her husband, becoming a national park ranger. Her character finds herself investigating crimes within park boundaries, frequently clashing with other law enforcement agencies over jurisdiction. Spiridakos previously appeared in a missing persons thriller film after leaving "Chicago P.D.", and her former character Hailey Upton recently resurfaced in a "One Chicago" crossover, confirmed to have joined the FBI.
