Through their music and their performance, they tell the story of a forbidden love; the love of a straight man (Johnny Switch), for a mannequin (Trannequin) who appears to be female, but may - or may not - be in the pre- (or post-) op stages of a female-to-male (or, male-to-female) transformation. This stage of uncertainty can be seen in what is likely to be their set-opener, Post-Op Pre-Op.

Popular music has historically tackled many taboos in its brief history, but few acts have been as brave as Trannequin in facing the strict moral codes and hypocrisy that are inherently rooted in contemporary approaches to gender norms and sexual mores. Trannequin seeks not to mock or ridicule those who feel that they must hide their love, but to hold a mirror up to our po-faced society and ask them serious, compelling questions, such as the catchy-yet-challenging Why Won't You Give Me Your Love?
