In the Capital Wasteland, Colonel Augustus Autumn and the Enclave unearth a pre-war quantum tunneling device called Die Nebenwelt ("The Other World"), designed to access alternate realities for resource extraction and conquest. Their attempt to test the device goes catastrophically wrong, tearing open a rift to an alternate 1953 Earth where the alien Chimera have overrun the planet. The rift destabilizes both realities, merging elements of the Capital Wasteland with the Chimeran-infested North America.
Nathan Hale, leader of the Sentinel program-superhuman soldiers enhanced by the Chimeran virus-discovers the Enclave's incursion and the rift's threat to his world. Meanwhile, the Lone Wanderer, a vault dweller from the Capital Wasteland, is drawn into the conflict after the Enclave's actions endanger their home. Autumn seeks to exploit the Chimera's technology and conquer both realities, while Hale and the Lone Wanderer form an uneasy alliance to close the rift and stop the Enclave before both worlds collapse.
