As BBC America's "Copper" neared its first season finale last fall, star Tom Weston-Jones suggested that his character, Det. Kevin Corcoran, is capable of forgiving those who betrayed him. (Season 1 spoilers ahead!)

The first trailer for the show's second season suggests otherwise, as Corcoran stares down his former best friend and fellow detective, Francis Maguire (Kevin Ryan). Later, Maguire pulls a gun on a man who from the back appears to be Corky, as Corcoran is called by his fellow officers working New York City's notorious immigrant neighborhood of Five Points in 1865.

In the first season, Maguire helped Corky search for his missing wife, Ellen, and a killer. Turned out he was faking it, as he knew exactly where Corky's wife was--and he was the killer they were hunting. To cover up his affair with Ellen while Corky was away fighting in the Civil War, he murdered both her abortionist and his own fiance, Mary. As for Ellen, well, she confessed that she was responsible for the death of her and Corky's daughter, Maggie.

I asked Weston-Jones if he thought Corky could forgive his wife or Maguire.

"I do really think anything is possible within this world. I think he could forgive her," he said, mulling the idea. "Then again, we all know what Corcoran is like. ... If anything were to happen again, or if anything were to upset him again, I think he'd become a rabid dog.

"Then again, he can also forgive. It just all depends how the story unfolds."

When the 13-epsiode second season begins at 9 p.m. CT June 23, Corcoran is struggling to rebuild his life while those around him strive to find their place on the rough New York streets. He has someone knew to worry about, too, in the form of Donal Logue, who joins the cast as Brendan Donovan, a Civil War general who has returned to his station in Five Points. The political boss of the Sixth Ward, Donovan is reasserting himself as one of the most influential and powerful men in the city's political machine.

"New York is fueled on secrets and lies," Donovan tells Corky in the preview above. "Let's not let the body count get any higher."

Sounds like Corky might be using his brass knuckles again, which Weston-Jones really enjoyed playing with in Season 1.

"I love those things. I really do," he said, adding that he wanted to take them home to London when he finished shooting the season. "I wasn't allowed. Also, I couldn't get them back on the plane. There is no way they would let me take them back on the plane. It's such a shame."

No doubt they were waiting in the props department when he got back to the Toronto set in February.

The Season 2 video also teases a counterfeit cash ring, a possible bank robbery involving Maguire, and a lot of shooting in the streets. We get a quick peek at Alfre Woodard, who guest stars as Hattie Lemaster, a former slave who arrives to the Five Points to start a new life. "Chicago Fire" star Eamonn Walker, Lee Tergesen and Andrew Howard also guest star.

Returning cast members include Kyle Schmid, who plays Robert Morehouse, the unruly son of a Manhattan aristocrat who is reeling from the consequence of his father's deceit and disgrace. Anastasia Griffith is the sophisticated Elizabeth Haverford, now threatened by exposure and ruin as a result of her double life. Franka Potente portrays Eva Heissen, the shrewd businesswoman who presides over Eva's Paradise, a brothel at the center of Five Points. Ato Essandoh is back as Dr. Matthew Freeman, now considering an expansion of his practice that means a return to Five Points.

Also returning are Dylan Taylor as Det. Andrew O'Brien, Kiara Glasco as Annie Reilly and Tessa Thompson as Sara Freeman.
