okay so I’m looking for an old (80’s maybe?) movie shown on a bad horror station in Spain. It’s about this teenage couple and the girl dies in a motorcyckle accident with the boyfriend. The boy just gets knocked out but when he wakes up and sees the girl dead, he drives her to an army station where he had heard his dad talk about some misterious chemical that they would use in battle (or something like that). This chemical turned the girl into a zombie of sorts throughout the course of the night (she didn’t look like a typical zombie though). At the end I’m pretty sure that the army captures the girl and there is a big scene where the guy is trying to save the girl but other people like the girl (zombies) are getting out of control and the guy needs to leave the girl and she dies.
