In a newly released The Last of Us clip from next week's episode 4, Joel and Ellie fight off violent raiders. The popular new HBO horror drama series centers on the relationship between survivors Joel (Pedro Pascal) and Ellie (Bella Ramsey) as they trek across a post-apocalyptic United States teeming with grotesque zombified humans who have been transformed by a deadly fungal plague. The two hope to safely reach the Fireflies, a militant revolutionary group that aims to use Ellie's natural immunity to the plague to save the world.
