Some folks are partying, a girl named Lou is dragged somewhere by a guy. Next the girl meets with some girlfriends complaining about not feeling well. They joke that she's pregnant. Some sinister guys are collecting urine from females in a fridge. One of them has her lips chewed off or something.
Lou in the meantime starts feeling weirder and weirder and sicker and sicker and indeed starts developing a belly. But that doesn't keep her from getting high non-stop. She has some weird visions. All this takes place in some poor town with a Marine base. There's an awful lot of talk and taking drugs and ridiculous music and silly visions.
At some point Lou meets a woman who seems to have some idea what's going on. She tells her that someone has implanted her with something. She suspects the government is behind this. With her help Lou tracks down some of the bad guys and we more or less find out what they are up to.
It doesn't take long for Lou to be full term and to give birth and here the movie manages to surprise. Some other characters also make an appearance and things do get interesting.
Antibirth focuses on a bunch of ugly people doing ugly things and who listen to hideous music. It's not easy caring about any of them or what's going on, which isn't really much. This is one of those movies, where everything that is said matters. At this pace the movie would have been a solid 2/10. But then suddenly the ending is pretty surprising. The movie works toward something, you know or hope that something interesting will happen, but at the same time you quickly give up. But then suddenly the movie does deliver and it changes one's perspective of the entire film for the better. Clearly a lot more could have been done with this script and the budget should have allowed for a better movie.
