We have three sneak peeks at AMC’s Low Winter Sun season 1, episode 4 airing this Sunday on AMC.

In these first two photos from this Sunday’s new Low Winter Sun we see Uniformed Cop (Luke Richmond) and Joe Geddes (Lennie James) in a tense discussion at the office:

In this third photo we see Simon Boyd (David Costabile) and a bruised Frank Agnew (Mark Strong). Viewers may remember Costabile for his role as Gale on another AMC show Breaking Bad.

According to the official synopsis for season 1, episode 4 titled “Catacombs,” “Frank plunges into a dark new world in search of Katia. Geddes deals with family issues. Tension rises in the blind pig.”

Low Winter Sun airs on Sundays following new episodes of Breaking Bad on AMC. In the series, aforementioned cops Joe Geddes and Frank Agnew murder fellow cop Brendan McCann and set it up so it looks like a suicide. The issue? Their Internal Affairs team investigating Brendan’s death found another body with the deceased officer, not to mention the cops have to keep their side of the murder a secret.
