HEADER portrays the grueling psychological journey taken by ATF Agent Stewart Cummings. On the surface...

Review 

Oh my God...If you go to church, pick flowers, smile at babies, pet kitties, or generally think people are kind and good, then HEADER is not for you. I left the theater in NYC with a pit in my stomach. I couldn't believe what i saw. what a story! I had to talk to my friends about it the rest of the night just to cope with what I saw. I still tell people about it, which is why i'm here now typing this comment. It's got to be seen. Very original plot. The acting was great, good film-making for an indie. I read a bunch of great reviews on the film too since i saw it, and these reviewers are as excited as i am about it. A desperate ATF officer, drug running, violent hillbillies, a sadistic legless old man in a wheelchair, the brutal act of Headers and a conclusion that surprised me and the gang I was with...It had to be the craziest flick i've ever seen. Edward Lee and Archibald Flancranstin are both going to hell.
