Steve is happy living on his wheat farm where he has everything he could need. If he doesn't have something he can visit the village to trade his wheat. But on one village visit he finds there's been a devastating Zombie siege, so, to protect himself and the remaining villagers Steve must go on a quest to mine for forty diamonds to craft into a diamond sword to shield the village from the Zombies.

On his quest he meets a trio of treasure hunters who are eager to join Steve on his quest. Facing treacherous mining conditions, a thunderstorm and attacks from hostile mobs, these four friends soon begin to question if it's better to be a single player than a multiplayer.

Will Steve find the diamonds? Should he trust his new friends or will they help his quest? And will he get back in time to save the villagers?
