S1·E11 Alone in the Dark Forest

Primus oceanography student Peter Holmgren is found hung during a class run, suicide after most surprisingly failing a crucial test, costing him one of only eight student spots aboard the new Goteborg university scientific ship's impending EU-subsidized Indian Ocean expedition, an ideal career boost. Classmate Albin Sundergart now gets his spot. Shortly after Marine biology professor Anna Norum, who failed Peter and the next day Albin's girlfriend Lynn Thorson is beaten in hospital, but first claims it was car, then she didn't recognize her assailant and waves police protection. Peter's shattered father Ingmar Holmgren is out for revenge. After a few days, Lynn Thorson's corpse in found, burnt and thrown down a cliff. Robert Anders finds Albin has no single alibi and had an affair with Anna Norum, which compromises her career, yet he denies Internet-posting the video they made of themselves in bed.
