Everyone, that is, but Arnold and a female POW. Arnie defeats the Predator, who detonates himself with a self-destruct mechanism/suicide bomb. Meanwhile, Arnie and the girl escape in a helicopter and the good guys win.
But After the Movie's Over ...
So ... when Arnold is in called to recap the situation to his superiors later, how the hell is he supposed to explain what happened to his team?
"I want an explanation without the words 'alien' or 'sudden river of acid'."
If he tells them it was an invisible alien, it doesn't paint a great picture of his mental stability. There is no sign the Predator was there other than a huge crater in the jungle. Yes, Arnold has the girl to back him up. But which is more likely, that a killer alien showed up on Earth, or that this crazy professional killer 1) murdered his squad and then 2) intimidated this woman into going along with his idiotic alibi?
We were already dialing for a chopper before we realized he wasn't in the room with us.
