In a prologue that reveals a young Indiana Jones (River Phoenix) in one of his first adventures, this thrilling screen epic continues as an adult Indy (Harrison Ford) embarks on a perilous quest for his cantankerous father, Professor Henry Jones, Sr. (Sean Connery). The Nazis are on the trail of the Holy Grail, and have kidnapped Indy's father, the foremost authority on the Cup of Christ. Follow Indy as he inches through the rat-filled catacombs of Venice, battles Nazi flying aces in a thrilling biplane dogfight, and braves the thunderous firepower of an unstoppable tank.
