In season 3, episode 7 of Power Book IV: Force, “Lines in the Sand,” Stacy Marks meets her ultimate demise when she tries to stand up to Tommy and no longer be under his thumb.

Season Three of “Force” stars Joseph Sikora (“Power,” “Ozark”) as “Tommy Egan,” Isaac Keys (“Get Shorty,” “The Oath”) as “Diamond Sampson,” Kris D. Lofton (“Ballers,” “Snowfall”) as “Jenard Sampson,” Manuel Eduardo Ramirez (“Snowfall,” “Queen of the South”) as “Miguel Garcia,” Carmela Zumbado (“You,” “Chicago PD”) as “Mireya Garcia,” Adrienne Walker (“Law & Order: Organized Crime,” “FBI”) as “Shanti ‘Showstopper’ Page,” Shane Harper (“Hightown,” “The Teacher”) as “Vic Flynn,” Miriam A. Hyman (“The Chi,” “The Laundromat”) as “US Attorney Stacy Marks,” Anthony Fleming III (“Prison Break,” “The Beast”) as “JP” and Lucien Cambric (“Chicago P.D.,” “The Chi”) as “D-Mac.”

I talked to Mirian A. Hyman, who played Stacy Marks, about why Stacy finally decided to be the “good guy” and why that ended up leading to her death, why she tried to find an ally in Miryera but not Shanti, and why Stacy was uncomfortable being controlled by Tommy and Vic and how it related to her own experiences.

Power Book IV: Force is now streaming on Starz, with new episodes on Fridays.
