When 'Vogler's Magnetic Health Theater' comes to town, there's bound to be a spectacle. Reading reports of a variety of supernatural disturbances at Vogler's prior performances abroad, the leading townspeople (including the police chief and medical examiner) request that their troupe provide them a sample of their act, before allowing them public audiences. The scientific-minded disbelievers try to expose them as charlatans, but Vogler and his crew prove too clever for them.

When disillusioned Swedish knight Antonius Block returns home from the Crusades to find his country in the grips of the Black Death, he challenges Death to a chess match for his life. Tormented by the belief that God does not exist, Block sets off on a journey, meeting up with traveling players Jof and his wife, Mia, and becoming determined to evade Death long enough to commit one redemptive act while he still lives.
