Polly Dipple and her brother Jack, two London street urchins, are rescued from hunger and cold by Dr. Barnardo, founder of the Barnardo Homes for destitute children. Jack is shipped off to Canada to work as a farm laborer, while Polly remains in England to train as a domestic servant. Eventually, Polly joins Jack in Toronto and the two of them are placed on neighboring farms. Badly mistreated by his employers, Jack runs away, but finally the two children are reunited and live and work happily with a farm couple who accept them as part of the family.
