Ray (Liev Schreiber) is determined to get Mickey (Jon Voight) out of prison in the upcoming episode 7, titled "Norman Saves the World," of the fourth season of the American crime drama "Ray Donovan."

As a possible way to set Mickey free from prison, Ray decides to ask for an old opponent's help to secure a bartering chip in the form of a comedy star. Ray also stumbles upon an old scandal, which brings him to a confrontation with a Hollywood agent and Ezra's (Elliott Gould) previous fixer. To top it all, the absence of Russian protection puts Ray in a risky place as he struggles to help Mickey maintain his security inside the jail and enter the tightly secured K6G prison wing.

The promo trailer for "Norman Saves the World" shows Ray visiting Mickey, warning him that he is no longer safe and it would be hard to protect him. Ray is also seen handing his initial deposit to his old opponent, whom he thinks would help him with Mickey's situation. It seems like Ray has to go through all sorts of unexpected trouble after learning a long-buried scandal.

Meanwhile, actress Embeth Davidtz talked about her nude scene in the previous episode, titled "Fish and Bird," where she showed her scars from her double mastectomy.

She told Vulture that her reps were initially concerned of the scene as she may be thought of as a freak by the viewers. However, she refused to look herself that way. She said, "This is a town where almost everybody's breasts have been sliced, diced, manipulated, and put back together. Mine haven't been, but this is part of my journey."

Even though some would view disfigurement as being ugly, Davidtz said that she thinks of hers as a battle scar. She added, "There are ugly battle scars and prettier ones, but they're part of someone's life, and I feel heroic in some way for having fought that battle."

"Ray Donovan" season 4 airs Sundays at 9 p.m. on Showtime.
