Question: Question: What kills Ion? If there is no answer, please output "Insufficient information to provide an answer.". Movie title: Caved In: Prehistoric Terror Context: The film opens in a salt mine in Switzerland in 1948. The miners are preparing explosives to blast new tunnels (and handling them none-too-carefully). It's ten minutes past six (ten minutes past finishing time), and the mining crew wants to go home. However Supervisor Frisch (Adrian Pintea)is determined that one last tunnel will be uncovered before he will let the crew leave. In this last tunnel the miners uncover a "bridal chamber" or small grotto filled with enormous green and blue gems. As the supervisor stands in the entrance of the grotto exclaiming in glee, a giant beetle descends from the ceiling. It is very similar to a stag beetle, but with an extra horn (like a triceratops version of a stag beetle). The beetle impales Frisch with its mandibles as more beetles swarm out of the grotto. The miners flee in horror, staggering back along the tunnels to the lift and getting picked off by the beetles as they go. One miner makes it to the lift which will take him to the surface; however at the last minute a beetle slices through his leg with its jaws, and he rolls in agony on the floor of the lift. He starts it though, and as he ascends, the detonator to the previously mentioned explosives is depressed by a hand, and the mine explodes, making the lift rock and sway. (It is unclear who blows it up. The miner on the lift does not have access to the detonator, however it is not clear who remains alive below to depress the detonator).We cut to a European forest scene, where John Palmer (Christopher Atkins) and his wife Samantha (Angela Featherstone) are at the end of a day spent guiding rich tourists through caves, assisted by their children Miles (Stevie Mitchell) and Emily (Chelan Simmons). Miles is 14ish and gung-ho keen, and Emily is 16-ish, whiny and reluctant(however when John tells Emily to head an hour back to the cave system to get a forgotten belaying rope she is prepared to do so!) We establish that Emily wants to be rich rather than work for rich people. The family is anticipating a much-needed...
