BBC America's new show Intruders is supposed to make Orphan Black viewers stick around after the season finale tonight (sobs), and is about body-snatching. I think.
The official synopsis describes it as being about "a secret society devoted to chasing immortality by seeking refuge in the bodies of others." But I don't think the trailer exactly gives that away, or anything, really. It's just a bunch of really disturbing images and I don't think we're supposed to know exactly what's going on.
Intruders premieres on August 23rd.
