When a car breaks down in the middle of the outback, a paranoid snitch finds himself trapped with his fellow thieves, and he must investigate them to survive.

Hmm. It’s kind of not clear enough for me. It sounds very tense and like a good contained thriller. But why does he have to investigate them to survive? I’m wondering if informant or undercover informant is what he really is? If he’s a snitch, did he already snitch or is he planning to snitch? I like it, it just leaves me a little confused and wanting a bit more information.
