When inept, self-proclaimed survival experts Kaduche and Wynn discover the world's impending destruction, they pull their act off YouTube and enter Epic Mode to save the Earth. Teaming up with their nemesis, the girl of their dreams, and an eccentric visionary known as the Oracle, the group sets out to battle domestic terrorists, disenfranchised Russian communists and brain-eating zombies.
