A man pours tomato juice over a pretty girl's dress to test a new stain and water resistant fabric.
In a laboratory we see several shots of Chief Research Chemist Raymond Priest testing two pieces of fabric; one is howcol treated, meaning it is stain and water repellent; the other is untreated. Raymond pours some blue dye both pieces of fabric; it stains the untreated piece, but just runs off the howcol fabric. Water is poured over the fabric; the howcol dries rapidly.
A girl, Angela Smith, enters and Raymond pours a tin of tomato juice over her lovely dress; Angela just watches calmly, then wipes the juice off with a wadge of cotton wool - there is no stain! This is like 'The Man in the White Suit'!
Note: according to notes and correspondence on file the laboratory was Eastman's, borrowed for the making of this film. They had nothing to do with the fabric, which was manufactured by the Rossendale Rayon Mills of Burnley.
