The power of the jungle, the wildness, the primitive emotions - they all come over Dorothy whenever she practises her Tarzan yell for the class play. Each time she does it, her yell becomes louder and more powerful, and the neighbourhood animals start acting strangely. When the circus comes to town, a puma escapes to Dorothy's yard after one of her yells. What will happen on the night of the play - which also happens to be the opening night of the circus - when Dorothy is determined to give the yell of her life?
