The Abyss

A group of tourists, mostly unrelated to each other, on their way to the mountains of North Bengal, find themselves on an ill-fated bus, that meets with a terrible accident. The bus falls off a cliff into an abyss, but the tourists are not killed. Injured and traumatized, in an abyss, far away from any human contact, they are left to fend for themselves and find themselves tasked with the challenge of climbing up the help in order to get help. How will they survive?
