Tira (Mae West) shimmies and sings in the sideshow of Big Bill Barton's Wonder Show, while her current boyfriend, pickpocket "Slick" (Ralf Harolde), relieves her distracted audience of their valuables for Big Bill (Edward Arnold). One of the rich customers, Ernest Brown, arranges a private rendezvous, during which Slick barges in and attempts to run a badger game on the customer. The customer threatens to call the cops, so Slick whacks him over the head with a bottle. Mistakenly thinking he has killed the man, Slick flees, but is caught and jailed.
Fearing that Slick will implicate her, Tira asks Big Bill for a loan to retain her lawyer, Bennie Pinkowitz (Gregory Ratoff). He agrees on condition that she does her lion taming act, which includes putting her head into the mouth of one of the beasts, promising her that it will get her (and him) to the "Big Show". It does. (West did some of her own stunts, including riding an elephant into the ring.[citation needed])
Tira's fame takes her to New York City, where wealthy Kirk Lawrence (Kent Taylor) is smitten, despite being engaged to snobbish socialite Alicia Hatton (Gertrude Michael). He showers her with expensive gifts. Kirk's friend and even richer cousin, Jack Clayton (Cary Grant), goes to see Tira to ask her to leave Kirk and his fiancée alone. He ends up falling for her himself. Tira and Jack’s romance leads to a wedding engagement.
Tira tells Big Bill she is quitting to get married. Unwilling to lose his prize act, he has Slick, recently released from prison, sneak into Tira's penthouse suite, where Jack finds him in his robe. As a result, Jack breaks off the engagement. Tira sues Jack for breach of promise. The defense tries to use her past relationships to discredit her, but the judge allows her to cross examine the witnesses herself and in doing so she wins over not only the judge and jury, but also Jack. Jack agrees to give her a big settlement check. When he goes to see her, Tira tears up the check, and the two reconcile.
