On a trip into Connecticut, Jessica Fletcher (Angela Lansbury) visits the affluent community of Cedar Heights, to review a manuscript with Lloyd Marcus (Norman Lloyd).
The widowed Lloyd Marcus' family consists of spoiled daughters Julia Granger (Anne Schedeen) and Sabrina Marcus (Andra Millian), as well as Julia's husband, Donald Granger (Christopher Allport), who shares a secret interest with Sabrina, beyond standard in-law affection.
Several other Cedar Heights residents frequent its Country Club, some without a viable means of support, including Mildred Tilley (Audrey Meadows) and her husband, the Mayor Frank Tilley (Gordon Jump), Staffer Ellen Davis (Deborah Adair) and Golfer and Art expert Binky Holborn (John de Lancie).
Attendant Forbes (Aubrey Morris) assists Police Chief Cooper (Cliff Gorman) with investigation a rash of art thefts plaguing Cedar Heights in recent nights, in which a burglar prowls for valuable paintings, and cuts them from their respective frame, whether or not "the Frame Fits."
But on the evening of a country club reception, various residents disappear from sight long enough to become suspects in a murder, once a body is discovered with evidence of a burglary, by someone who tidies the room to implicate another in order to frame the intended stool pigeon "If the Frame Fits."
Jessica assists Police Chief Cooper in the resulting investigation, which includes conflicting allegations of intent, and conflicting theories regarding the burglaries and murder.
The cast is rounded out by Michael Morgan as Young Man, and Russell Merritt as Waiter.
