Cinema publicity film for Eve Shampoo.

Two detectives question a maid and a publicity officer at a theatre where the leading lady has disappeared on the eve of a premiere of a new performance, causing much speculation in the newspapers. Later they compare two hairs found in the stars dressing room under a microscope. One is clean and shining the other is dull and covered in soap deposits. One of the detectives knows that the star uses Eve Shampoo which contains no soap and concludes that the maid must have been in her room and that the publicist is in on the act.

The show goes on to a full house and the chorus girls admire the star's hair. Details of how to buy Eve Shampoo as a cream or as powder are given.
