Detective Inspector Frank Frølich finds himself lying on top of an attractive woman during a routine police raid, but they don't meet again for some time. When they do there's an immediate sexual attraction between them and they start a passionate affair. There's only one problem - Elisabeth is the sister of Jonny Faremo and the police know him all too well - but by then it's already too late as Frølich is obsessed. When the bodies start piling up he has to find out if Elisabeth feels anything for him or if she's using him. By then he's been suspended from the Oslo police force and is suspected of being involved in various crimes.
