Hank Whirling needs a bank loan to keep his Whirling Circus going. He gets it from a stuffy New York City bank, but only on the condition he take along accountant Randy Sherman and publicist Helen Harrison to help the circus turn a profit. Hank's top act is the Colino trapeze troupe, featuring family patriarch Zach Colino and newcomer Tommy Gordon, as well as ringmaster Hans and clown Skeeter. Unknown to Hank, his little sister Jeannie has held a lifelong ambition to fly on the trapeze and has been secretly training with the Colino act for the past year.
