Our hero is Umbi (an acronym for emissary of the bishop), sent by him to undertake an important investigation at Snæfell-glacier. In particular he is to look into the conduct and behavior of Jón Prímus, the old pastor at Snæfell. Fantastic rumors are rife: amongst other things it is said that a corpse is lodged in the glacier! Armed with his tape recorder and notebook, Umbi embarks upon his mission. He tries to question the weird locals, a weird lot, but gets evasive answers. Slowly he is dragged into a quagmire of strange happenings and his efforts to understand only make him confused. If at the beginning he is a chipper, a mere device, by the end of the story he is inextricably involved, a committed participant in the bizarre events.
Unfortunately the movie Under the Glacier is not yet available on HBO Max.
