Alf, Mrs Hollingbery and Arthur are still staying with Mrs Hollingbery's rich brother Ricky in Australia. Ricky and his wife Railene take them off on a trip to the outback; Alf is terrified and his fear is not helped by Ricky's practical jokes. What has so far been dislike, now becomes open war between Alf and Ricky, particularly when Alf discovers that Ricky's 'generous' offer to lend them the money to buy their council house in London may not be all it seems.
