Eleven Gilbert & Sullivan numbers are melded within the murder-mystery plot of "Girl on the Spot", with a result that either G&S and/or the plot are always seemingly on stage-wait or in the wings awaiting a cue. Lois Collier is the girl-on-the-spot of the title because she was on the scene of a murder. The police conclude she didn't do it and they use her to set a trap for the real killer, a G&S addict, by financing a Broadway production starring Collier.
