Eccentric scientist, Professor Jeremy, creates a truth serum. After experimenting on his cook, revealing her secret whiskey and cigar smuggling, the serum accidentally splashes on Thorpe Willis, a reporter, who confesses his deepest feelings. The professor, annoyed by the widespread attention and requests for the serum, destroys the formula and secures it in a safe. However, a crook, "Smoothy" Smithers, steals the liquid, drops it, and publicly confesses to a burglary. Ultimately, the reporter, Thorpe, crafts a hoax about the serum, and the professor accepts him as his son-in-law.
