A dodgy detective (Terry-Thomas) is retained by a dotty dowager (Anna Russell) to investigate shady-goings on at her favorite health spa by posing as a patron. When his client gets poisoned on the premises, however, he must partner with the retreat's shaken manager (Eric Sykes) to flush out the culprit. Fitful farce co-stars Dennis Price, Lionel Jeffries, Ronnie Barker, Moira Redmond. 98 min. Widescreen; Soundtrack: English Dolby Digital mono.
