Today I saw a tweet by K$
After a little search (there is a movie with the same title from 2012) I found this:
After wrapping the third season of A&E’s Longmire, Bailey Chase (Saving Grace, Buffy the Vampire Slayer) is heading to New York this month to film indie drama Kill For Me. He’ll star as Charlie Sundstrom, a newly released ex-con who must navigate the criminal underworld to save his son, unaware he’s being set up to pay for his crimes all over again. Tim McCann is directing from a script by Raymond Kwok. McCann and Kwok are producing with Ben Bickham while Linda Moran and Rene Bastian are exec producers. Chase plays Deputy Branch Connally on Longmire and will appear in the upcoming drama Sex, Death, and Bowling with Selma Blair. He’s repped by Untitled Entertainment and The Gersh Agency.

Studying Bailey Chase's twitter and facebook looks like Kill for Me is filmed in Albany, Amsterdam, Mt McGregor and Amsterico, NY from July 15 and still going on. I can't find anything about Kathryn's roll yet. Nevertheless, yeah a new Kathryn project!!!
If you want to see a few more on set pictures of the filming (without Kathryn) just scroll through the twitter timeline.
