Steve lives on a wheat farm. He has everything he needs to live in the Minecraft world: a bed, a house, and food. Steve likes to spend his mornings in the NCP village and trade his wheat for emeralds, armor, books, swords, and food. One morning, he finds that Zombies have attacked the villagers. The Zombies have also turned the village blacksmith into a Zombie, leaving Steve without a place to get swords. To protect himself and the few villagers that remain, Steve goes on a quest to mine for forty diamonds, which are the most powerful mineral in the Overworld. He wants to craft these diamonds into a diamond sword to shield him and the villagers from the Zombies. Far from his home, with night about to set in, Steve fears for his life. Nighttime is when users are most vulnerable in Minecraft. As he looks for shelter in a temple, he meets a trio of treasure hunters, Max, Lucy, and Henry, who are trying to unearth the treasure under the temple. Steve tells them of his master plan to mine for the most powerful mineral in the Overworld--the diamond. The treasure hunters are eager to join him.
Facing treacherous mining conditions, a thunderstorm, and attacks from hostile mobs, these four friends question if it's better to be a single player than a multiplayer, as they try to watch out for each other and chase Steve's dream at the same time. Will Steve find the diamonds? Will his friends help or hinder the search? Should he trust his new treasure hunter friends? And will Steve get back in time to save the villagers?
