Contemporary reviews of Beerbohm Tree's production offer the following synopsis:
'[Its] story is mainly concerned with the proceedings of a certain lawless individual who, after a career of bush-ranging in Australia, obtains a footing in an English county family, becomes engaged to a charming girl, then, being wanted by the police, takes an unceremonious leave of his fine friends, and finally cuts short his career with a revolver.'

Captain Swift, a bushranger, swaps identities with a man he finds dead in the Australian bush, and returns to England to begin a new life.
'Michael Wilding, an Australian in London, is invited to the exclusive home of the Seabrooks. There his stories of the Australian outback interest some of the reserved English family, while others are suspicious of his background.
'There is good reason for this suspicion. Due to a whole tissue of coincidences—which it would be unfair to disclose —it soon appears that Michael Wilding may be no other than Captain Swift, a young Robin Hood-type bushranger who has recently disappeared from Australia. But by this time Michael is deeply involved with the Seabrook family.'
