A sequel to the 2012 sci-fi comedy, "Iron Sky." 20 years ago Earth was ruined in a nuclear apocalypse. What's left of humanity is trapped on the Moon - which is now falling apart as well. Mankind's only hope is to send a small team into the Center of the Earth to retrieve the mythical Holy Grail. All that stands in their way is an ancient race of reptilian humanoids and an army of dinosaurs. How hard could it be?
