Dr. Marshall Cahill is the director of a government institute that employs various scientific geniuses, including the elderly Dr. Nicholson, who knows that Cahill's son Neil has plagiarized a dead man's theory of molecular structure. When Nicholson threatens exposure, Dr. Cahill murders him and cleverly makes the killing look like the job of a heroin junkie who needed his fix. But clever or not, another kind of genius is on the case: the rumpled, redoubtable Lt. Columbo.

You don't seem too pleased.
Well, you know, Doctor, I've been running into people by the dozens who couldn't have murdered Professor Nicholson. I wish I could run into one who COULD have.
