What if one of the most important medical discoveries in history happened because of a messy laboratory?

Travel back to 1928 and explore how an accidental contamination transformed modern medicine, saved countless lives, and proved that sometimes the biggest breakthroughs come from the most unexpected mistakes. A ruined experiment. A lucky observation. A discovery that changed the world forever.
