Sanctum? Damn Near Killed 'Em.

A hot chick, a reckless daredevil and a safety conscious wet blanket find themselves trapped in a huge underground cave. With only cheesy one liners to keep them company they must find a way out, back to the surface, before their mates piss off home for their tea and forget about them. It’s like the Poseidon Adventure but with more bad acting, sleeveless vests and hard hats…and it’s in 3D!
