The body of a young woman is found in a Stockholm hotel room. It appears that she has been strangled after a night partying with two young men, but the room was paid for using the credit card of a mugging victim whose alibi doesn't add up. Martin and Gunvald investigate under the supervision of their new boss Klas Freden.
Unfortunately the movie Beck 27 - Rum 302 is not yet available on HBO Max.
