Næturvaktin revolves around the lives of three employees working at the Shell petrol station in Laugavegur, Reykjavík. The three man night shift is made up of eccentric supervisor Georg Bjarnfreðarson, a committed Marxist, vegan, who has an admiration for everything Swedish. Ólafur Ragnar, a regular employee and a simple, well-meaning guy who dreams of fame and wealth. And Daníel Sævarsson, who after dropping out of medical school joins the team.

What the three men don't know is due to this job how profoundly their lives will be forever linked.
