A London banker's son, already once indebted for gambling, is accused of theft from his father's office and banished to Australia. Finally his innocence is proven but his father's letter requesting him to return falls into the hands of a fellow shepherd and friend on the North Queensland sheep station where they work. His 'friend's impersonation of him fools all but the youth's betrothed - and he finally returns to her on his father's deathbed. (PB)
