Roscoe, a seasoned circus dog, is growing old.
Tricks he once performed with ease are getting difficult.
Luckily the new puppy, Rolly, is a quick learner.
She helps out her old friend, who is worried that one day he'll get fired from the circus.
When a crisis interrupts the Christmas performance, it's up to old Roscoe to save the day! His golden heart and incredibly sensitive nose come in handy.
As Roscoe himself says, I may forget everything else, but I will never forget the smell of a child.
