Hex (2018)

Ben (Kelly Blatz) and Amber (Jenny Boyd) meet up in the idyllic heat of tourist Cambodia. They are immediately physically attracted, but what do they really know about one another? As Ben gets sucked in to Amber's vortex of nasty ex-partners and debilitating physical ailments, he forgets to question what precisely Amber is getting from their relationship, this results in one of the more beguiling and unnerving of closing sequences.
