We saw some of this last night and I was surprised to find it was a reality show. The brief clip I'd seen somewhere had led me to think it was some sort of 'hilarious' comedy based along the notion of a True Lies type cover up by the main character. It's actually pretty good, though. Sandra seems quite normal woman who happens to like guns and catching bad guys.
The guy she was after had 'Suicidal' tattooed on the front of his neck and the discussions about how he must be a total nutcase before hand were pretty funny, as was her getting him to open up by showing him her tattoos: "It used to be up here but I've had two kids now so there it is."
