Wealthy widow Flora Melkiot is not happy. After what was just a little traffic accident her loving – and painfully proper – daughter Clarissa whisks her to a rehab/nursing facility for the elderly near her own home in San Antonio. She even gets a temporary guardianship so Flora cannot leave to continue the free and not always conventional lifestyle which Clarissa finds so embarrassing.
The brutal murder of the very unpleasant widow of an Air Force general inside the nursing home brings Flora’s curiosity to a boil, so she and Dewayne Harbaugh, a badly handicapped but unquestionably brilliant fellow patient, decide to solve the murder. Another resident, a more-than-slightly dotty little old lady, is murdered and this time Flora is the prime suspect. Only after a savage assault on yet another patient does Flora start to see the glimmerings of a solution, but can she make anyone believe her before her own life is brutally snuffed out?
