Never did watch this show, but the name sound like something similar to 'Battle Royale'. Hmm... better bring me an ak47 along.
I haven't watched 'Battle Royale', but I've seen the plot.
In Survivor, every 3 days, they vote someone off the island/location.
In Battle Royale, they put a whole class of (9th graders in case of the film) on an island with collars on them. They are supposed to kill each other until 1 is left. If they break the rules, their collar explodes. Fairly violent movie but made in Japan.
