Larry Haines, a mediocre vaudeville entertainer, boards a train bound for Los Angeles. Is Hollywood waiting for him with open arms? Not really as the one he signed a contract for is Percy, his roller-skating penguin partner! But, as the proverb says, the shadow of glory is better than no glory at all! Anyway, doesn't Larry meet a woman on the train? And a blonde one! And a British agent into the bargain! The delicious creature who is carrying a coded message hidden in a brooch and is being pursued by Nazi agents. She will need Larry (and Percy)'s help to elude her pursuers and to get the secret information to destination. The mission will be accomplished, although in an eventful and hilarious way...
