Edgar Greenstreet (John Hillerman) operates Marathon Toys, a New York City corporation which produces a wide assortment of elaborate toys and games.
Executive Vice-President Meredith Delaney (Barbara Babcock) usurps power as she controls its stock and employees alike, calling Edgar an eccentric, who ought to be banished from the corporation.
Meredith manipulates her young husband, Project Supervisor Devery McFarlane (Harley Venton), her devoted Secretary, Sylvia Moffett (Hallie Foote), Marathon Toys Designer, Frank Christy (Ben Slack), and Reporter Stromberg (Robert Ackerman), banning him from the premises.
Meredith conducts an affair with one Advertising Agency operator, Boris Steloff (Joel Fabiani), and plays him up to compete for a contract against Preston Advertising Agency operator Miles Packard (John Petlock), who employs Amanda North (Caroline Williams) and Brian Singer (David Lansbury).
When Jessica Fletcher (Angela Lansbury) arrives at Marathon Toys to consult the production of "Murder Will Out," a board game designed from one of her Mystery books, someone secretly slips into her purse a code to unlock a secret chamber, B100, a toy production factory inside the corporate basement, to which only eight others may access, inside which Edgar Greenstreet emerges from a secret panel to greet Jessica.
Devery McFarlane is assigned to oversee Jessica's project, while Brian Singer serves as Jessica's escort to dinner and to Marathon Toys' Silver Jubilee Celebration, at which five receive performance awards.
Brian admits to Jessica that his association with Amanda reaches beyond business even though she uses him to advance her career, a factor Meredith takes into consideration when she advises Boris to hire Amanda from Miles in order to receive the advertising account, but not to romance Amanda or else.
Brian then disappears from Jessica's sight at the Silver Jubilee, but when she searches the building, she encounters Edgar Greenstreet in B100, where, together, they discover a body encircling the basement in a train car, after being bludgeoned by a crow-bar.
Lieutenant Hornbeck (Leo Rossi) arrives to investigate the murder, which he deems a burglary gone wrong, as top-secret Project 2100 evidently has been stolen.
Upon testing the crow-bar for fingerprints, the police laboratory discovers only Brian's, and when Lieutenant Hornbeck arrests Brian Singer, it is up to Jessica to prove Brian's innocence, and to champion young love, as no one else would be worthy of Amanda's hand for some reason amid this "Murder On Madison Avenue."
