It would probably work better as a comedy series, but I'd love to read or watch a story about a group of three conspiracy-believing idiots who manage to sneak aboard a scientific ship headed to antartica to try and prove that the earth is flat. However, disaster strikes and the ship sinks just off the coast, only for the three idiots and one scientist to survive. They have to band together to survive the aric, and end up losing their way.... and discover that the world is actually flat when they run into a giant wall of ice that extends farther up than anything could exsist and just never ends.

The main character is actually the scientist who is grappling with the idea that these three idiots he has to deal with are actually right, and he's fallen for the round earth propaganda. Maybe they run into the actual scientists who help maintain the lie that the earth is flat. I dunno.

But I like the idea of it.
