For us, harvest festivals are about rummaging around in the cupboards for tin cans to give to charity. For the Sumba people in Indonesia, it involves a bloody fight - sometimes to the death.
The festival is called pasola, and VICE magazine have put together a film called Blood Sacrifice in Indonesia’ to give a rare glimpse into the ritual. It's an annual spear-throwing battle that takes place on Sumba, a place which was isolated from the rest of the world.
Now the Sumba people and the ritual may end up a thing of the past, as tourists who come over to the island from Bali may upset the balance. Certainly the islanders aren't averse to western influences - the team meet one of the island's most respected warriors who shows them his hut and...Britney Spears posters.
Presented by VICE correspondent, Milène Larsson, the film follows the lead up to the Pasola, the event itself, and the bloody aftermath.
VICE said: "If you kill someone during the Pasola, there are no repercussions and you don't go to jail; the local traditions are so ingrained that the Indonesian law system steps back and lets local priests called Ratus handle business. Decapitations still happen on the island, so ritualised violence like during the Pasola provides a way of resolving disputes between the clans without too much bloodshed.
