El misterio de los almendros

In this modern Mexican crime drama, two handsome young private detectives are hired to investigate some possible criminal goings-on at a large estate owned by a wealthy widow by the name of Dona Josefina. There's one catch, however; Dona Josefina is very "open minded", and so her guests are artistic, decadent, and homosexual. In order to get an invitation, our two investigators must pretend to be gay!
