Blood Paradise (2018)

Reeling after her latest novel flops, best-selling crime writer Robin Richards is sent by her publisher to the Swedish countryside to regain inspiration. There alone, she indeed comes across an assortment of peculiar characters, including her driver and most obsessive fan, his explosively jealous wife, and the progressively more unhinged man who owns the farm that's hosting her. Totally out of place in her new surroundings - for one, she is always dressed for glamorous, big-city life - Robin discovers just how dangerous the life in this East-European country may be.
