Seven Men and One Brain

Criminologist Ross Simpson seems to have everything that one could desire; the respect of his university students, being an author, and having a secret identity. The only thing Simpson doesn't have is a large amount of money. Simpson's secret identity involves planning what he regards as perfect crimes, however they fail due to the stupidity and bumbling of the criminals he recruits to carry out his secret schemes.

Simpson's publishers send him on an all expenses paid trip to Buenos Aires that includes accommodation and an attractive secretary. Putting his writing on hold, Simpson schemes to rob the patrons of the Teatro Colón during the opening performance of La traviata using a gang of Argentinian criminals who are trained to sing. Things begin to go awry when Simpson is pursued by the angry Italian criminals who failed on one of his Italian jobs and a variety of sexy women who seem to get in his way...
