Does anyone know what movies im talking about?

Okay so i watched this movie a few years ago %26amp;nd i really liked it but idk what its called %26amp;nd its been really bothering me lately.



So it was on Sci Fi %26amp;nd it started out with this dude %26amp;nd his girlfriend. His dad worked with the government. Like on top secret stuff %26amp;nd unnatural things like zombies %26amp;nd vampires %26amp;nd stuff. So the dude was kinda rebellious, %26amp;nd one day he %26amp;nd his girlfriend sneaked into some secret lab thing his dad worked for. There they found this human//vampire//zombie thing. Something happened %26amp;nd the human//vampire//zombie thing came to life %26amp;nd bit the guys girlfriend. It was chained to the bed though. Then it went dead again. So then lalala stuff stuff stuff ( i can't remember ) So their like in a car %26amp;nd the girl is saying she's extremely hungry, like to the point of starving. He stops at a gas station %26amp;nd she runs in an opens a twinkie. Then i guess they get out of the store %26amp;nd some how they end up in a cops car. The guys in the front driving the car %26amp;nd the girls in the back with the cops. She sucks there blood out. O_O So the dudes extremely confused %26amp;nd terrified im guessing. %26amp;nd then i can only remember the last part, when theres like this gate %26amp;nd on one side there the guys dad %26amp;nd on the other side theres fire %26amp;nd his girlfriend. He's in the middle. his dad tells him to come back but the guy says something like ';No dad, i belong in this world.'; %26amp;nd walks with his girlfriend into the fire.



Like i said i watched it a few years ago, %26amp;nd it looks like it was made in the 90's or something. Does anyone know what im talking about?!Does anyone know what movies im talking about?
