The circus elephant Helmut has vanished just before the show, so clumsy detective Jonathan is called in. He stumbles into the chaos, becomes the overexcited circus director's assistant, and is accidentally hailed as a hero. Children in the audience help solve the mystery with shouts, laughter and clues. The show blends acrobatics, comedy and audience participation, runs about 50 minutes, and suits ages 2 to 11; wheelchair users and people with disabilities attending with a companion can arrange tickets and seating in advance.
