Hi there,

Only some from that movie:
- in this movie, the main villain were running a group want to bring Satan back, his plan is to rape his daughter so her will gave birth for Satan
- in one scene, main villain took a giant snake or python from girls belly, totally scary for me 
- in final scene, the guy who act main heroes killed main villain by stab in the seal in main villain head, now transform to an dragon or something like that
And, this movie contain a lot of bloody violent and sexual scene.
Some one please help me what is this movie?
