Being a lady detective is hazardous enough under the best of circumstances, but when your client decides to play his own dirty trick and double-cross you, it becomes decidedly more so. Fanni dons her cat-suit, grabs her silenced Model A, and sets out to find the missing Lisa. But the double-cross turns into a triple-cross with Fanni tied, gagged, and whipped with a little Lisa holding her leash and Fanni's long standing, arch enemy, Tonya, looking on. Now all Fanni has to do is get loose, capture little Lisa and Tonya, and enjoy a little revenge. Easier said than done!
