Roscoe, a seasoned circus dog, is growing old. Tricks he once played with ease are getting difficult even mental calculation, which has always been his strong suit. Luckily the new puppy, Rolly, is a quick learner. She helps out her old friend who is scared to be thrown out of the circus. In the final show of the season, it is Rollys turn to shine as the star. An unexpected incident interrupts the show, and old Roscoe is needed again. The golden heart and incredibly sensitive nose of his come in handy. I may forget everything else, but I will never forget the smell of a child, the old dog sighs, content.
