Sgt Howie meets with the Lord Summerisle (Lee) and finds out that they are all pagans. Convinced they have murdered the girl, he tries to leave on his sea-plane but finds it has been sabotaged. He makes his way back to the island, and follows the main procession - disguised as one of the costumed performers.
He gets past a possible decapitated-scene unscathed - but then spies the missing teenager and follows her into a cave. He is led into a trap, and imprisoned inside of a giant statue made of wicker among with a load of other animals.
Under the guidance of the island rulers, they set fire to the wicker man and sacrifice Sgt Howie to hope for a better harvest.
