In Tuesday’s newly released trailer, Ruth receives a chilling call in prison right before she’s set to be released. As she picks up the phone, a voice tells her, “You’re gonna pay for what you did.”

While the trailer doesn’t share what Ruth’s “violent crime” was, she does say that whatever she did was intentional, not an accident.Viola Davis' character reveals that Ruth “killed somebody in cold blood,” while Rob Morgan’s character calls Ruth “a cop killer” later in the trailer.
