It is April 6, 1917, and the most powerful nations in the world are embroiled in a war the likes of which humankind has never seen. An aerial reconnaissance team has noticed that the German army is in the middle of a tactical withdrawal from the Hindenburg Line. However, British forces stationed there believe them to be retreating, not knowing of their oppositions true intentions to wipe them out with artillery. The field telephone lines have been severed, so the only way to deliver this valuable information is for it to be conveyed in person. General Erinmore sends two young soldiers, Will Schofield and Tom Blake, to deliver the message to Colonel Mackenzie, who leads the Second Battalion of the Devonshire Regiment. The fate of 1,600 men hangs in the balance.
Thor, Loki, Hulk, and the Asgardians have left their home world following an event known as the Twilight of the Gods – Ragnarok. However, their spaceship has been intercepted by the one who orchestrated Loki’s attack on New York City: Thanos. The Mad Titan has recently acquired the Power Stone from Planet Xandar and will stop at nothing to obtain the remaining five. The Infinity Gauntlet Thanos bears will unlock the Infinity Stones’ true potential. With them all in hand, he intends to kill off half of the universe’s population. With the Avengers divided thanks to the efforts of Colonel Helmut Zemo, Earth’s mightiest heroes will need to do everything they can to prevent Thanos’s unconscionable ambitions from coming to pass.
