Last week, we told you that Sarah Michelle Gellar was headed back to television for an all-new series called Ringer. But aside from the fact that the CBS show deals with a woman on the run assuming her wealthy twin sister's identity for cover, we don't know a whole lot about Gellar's new gig. To that end, Ringer producer Peter Traugott provided Entertainment Weekly with a detailed look at the story and characters of Ringer.

Speaking of the premise, Traugott said:

“It’s an edgy thriller about redemption and about revenge. There’s a point of view of two twin sisters who grew apart over a tragedy in their past. And one now seeks redemption and the other one seeks revenge. The sister who is seeking redemption has had a much more troubled life. When her fancy pants sister disappears, she takes over her life. She’s living the life of her more successful sister only to come to find out that her life is equally as fraught with danger and complication. Her sister dies in a boating accident. The other sister takes on her persona, only to come to find out that they have a hit out on her.”

So, is Gellar playing both sister roles, then?

“She plays two characters: One is Bridget, the sister who takes over Siobhan’s life—Siobhan’s the other sister. The sisters reunite after having been estranged for a long time, and when they reunite, Siobhan dies. She falls…you know, in a boating accident.

“You’ll see [Siobhan in flashbacks]. Not necessarily tonally nor stylistically, but the show comparable to Damages. I love Damages—by the way, it’s my favorite show—but in the same way that Damages tells part of the story in the present, through the past. Not just flashbacks but through actual stories in the past. That’s what’s happening here. Hopefully if we go to series, the audience will come to understand what the fall out was between Siobhan and Bridget. Why Siobhan would never want to see her sister again, why Bridget was in a kind of dark place in her life—all that stuff will be told as we move forward in Bridget’s stories through flashbacks with Siobhan."

Are there similarities between Ringer and Buffy, or is this totally different?

“It’s a very different show. I mean, Buffy is so specific and a great, cool genre piece ... But in the same way with Sarah, I think what’s remarkable about her as an actor—and very few people have this ability—she can play both sides well. If you remember Cruel Intentions, she was the villain, but you found yourself kind of rooting for her anyway. That’s what we’re looking for. How do we find something where her character has some edge, there’s some darkness to her, she doesn’t always do the right thing, but at the end of the day, you’re also rooting for her? And that’s what we were looking for in this. Obviously, Buffy was a hero, a kick-ass hero, and we wanted to be true to that with Sarah.”

That's just the tip of the iceberg, so check out the full report for more.
