The Brokenwood Mysteries S01E04 - Hunting the Stag

Four close friends go hunting in the bush on a stag trip. But the groom-to-be never comes back - he was shot through the head. Initially this would seem to be just another tragic hunting accident amidst picturesque New Zealand bush. The only problem is neither of the remaining two friends own up to pulling the trigger that fired the lethal bullet - yet all three had discharged their rifles - with no deer to prove it. The question is - who shot Hayden Renner? Was he mistaken for a real stag or was there something more sinister at play?
