Joseph Campbell's idea of the monomyth, the single hero's journey he claimed underlies myths across every culture, gets tested against four very different stories. The film follows the Slavic tale of Ivan and Koschei the Deathless, tracing motifs of trickery and cheated death that echo far beyond Russia. It moves to the roots of King Arthur and the wizard Merlin, examining how a British warlord became a legend with a sorcerer at his side. Odysseus gets his turn too, resisting the Sirens' song on his long road home, before the film closes with Sigurd's fight against the dragon Fafnir, a story that fed directly into Norse and Germanic legend and later Wagner's operas. Narration and expert commentary link each tale back to Campbell's structure of departure, trial, and return, while also noting where the stories break the pattern. The result is less a single argument than a guided comparison, letting viewers see the recurring shapes myths keep reaching for across centuries and continents.
