Marx and Venus get ready for a Saturday night on the town. When Venus spies Marx dressed in a dull grey shirt, she talks him into trying on a spare colourful shirt she happens to have. While he's not thrilled at wearing another man's clothes, he looks fantastic in the shirt. With the music playing and the drinks flowing, Marx soon loosens up with the help of the outfit, and Venus' company. They both head out to start their nights, separately. However, in the morning things seem a little strained, even weird, between the flatmates and there's a long unanswered question about what exactly happened the night before…
