Two young lovers are hysterically in love. The girl's father opposes their marriage, so the lovers elope but fail to consummate their wedding. "Sganarelle," a roadside potion peddler, is coaxed into assuming the guise of a prominent physician. He prescribes cannabis, his preferred and only medicine. While curing some ailments of the local gentry, he is coaxed into attempting to cure a young girl's horrific ailment that is caused by the forbidden love between her and her first love. The accidental doctor uses his prowess as master of cannabis potions and vapors to concoct a comedy of errors in this farcical homage to Molière and Machiavelli. All of the players' altered personalities, the maniacal misunderstandings, the salacious events, and the pain of young love end with the humiliating defeat of the villainous representative of Big Pharma.
