In a world of fantasy, adventurers come far and wide to join the Guild, in order to complete contracts for whatever jobs are available. An inexperienced priestess joins her first adventuring party, but comes into danger after her first adventurer contract involving goblins goes wrong. After the rest of her party is wiped out, she is saved by a man known as Goblin Slayer, an adventurer whose only purpose is the eradication of goblins with extreme prejudice.
