(In Swedish with English Subtitles) He's got no style, he's got no flash and he's squarely in middle age. But Swedish detective Martin Beck is good at one thing: methodically catching criminals so that they can be put away... for a long time. His tightly-wound partner, Gunvald, is his opposite: an impulsive man who cuts a dashing figure, is in no way politically correct and who never met a boundary he didn't leap across. He'll do anything to get information from a suspect, including enhanced interrogation techniques. It's classic good cop/bad cop, and together with their team they bring down dangerous criminals lurking in the seedy Stockholm underworld. Beck's a loner but he's not anti-social; he regularly sees his daughter, with whom he now has a much better relationship than when he was neglecting her growing up. And at the end of a workday, there's always an interesting conversation and a nightcap with a neighbor who gives new meaning to the word quirky. EPISODE 4: SERIAL KILLER - a serial killer is on the loose. All the victims are women, and all attended the same school. Beck digs deep into a past no one wants to re-live, in an effort to unlock the mind of a deranged lunatic, and to prevent the ultimate act of revenge. EPISODE 5: THE PEARL HOTEL - a young girl dies after being hit by a car driven by Beck's trusted deputy Gunvald Larsson. Meanwhile, a taxi explodes at a ferry terminal on the Baltic coast. Beck needs Gunvald's help to crack the case but can he bring him back from the brink? EPISODE 6: THE MONSTER - Responding to an anonymous threat, the Stockholm bomb squad detonates a suspicious suitcase. Inside the tattered remains of the bag, they discover the body of an infant. Beck leads the investigation to hunt down the man responsible for this grizzly set-up, a man the newspapers are calling the Monster.
