Flop vaudeville performer Len Carmody is adopted by Kelly, a trained dog abandoned by Malo's dog act. When Kelly joins Len's ho-hum song and dance, a popular comedy act is born. On the train, Len meets young Mina Van Runkel, daughter of a movie producer in desperate need of new talent (it's 1930). Successful in making "dog pictures," can Len stand being second banana to Kelly? Complications: a pallid romantic triangle...and the reappearance of Kelly's original owner. Written by Rod Crawford
