Explain 'Shutter' (Thai horror flick) to me [SPOILERS]

Too stupid to watch horror movies I guess…

Jane and Tun are in a car and hit a pedestrian and drive off, and she (presumably) dies and then proceeds to haunt them.

Then the plot sort of hangs a right turn without signalling first: Tun’s friends start dying and one of the wives or girlfriends yells at him that they must’ve done something to deserve this, “that gang of yours”. Which is QUITE odd because no one but Jane and Tun were involved in the auto accident, why would she (the dead person) punish Tun by killing his (uninvolved, innocent) friends? As it turns out, (and as the plot’s unsignaled turn becomes a hairpin), there’s another girl involved, also dead, once Tun’s girlfriend except maybe he wasn’t so friendly to her and did not stand up for her when his “gang” friends start picking on her. Oh, OK, but what’s that got to do with the girl that Jane and Tun hit with their car? Who knows, the movie never, ever, goes back to her again.

Me: :confused:

I’ve only seen the US remake, but what you’re describing sounds very similar so…

[spoiler]In the remake the girl they “hit” in the beginning is the same girl as the one who was being picked on. She was already a ghost by the time the main characters hit her with their car.

The guy’s friends raped the dead girl, who was the male lead’s ex-girlfriend, so that’s why they begin to die - you know, the vengeful ghost thing. He’d asked them for help getting rid of her, and though they might have just meant to scare her at first, things went very badly… [/spoiler]

OK, that does make sense. They were probably kind of sparse in translating whatever dialog would have clued me in that such was the case.
