1x18 - The Adventures of the Scarlet Pimpernel

The Pimpernel rescues Andre, one of his agents from Chauvelin, but has to find Jeanette, the man's daughter, before Chauvelin does. Disguised as a farm worker, he seeks a job at a farm owned by the girl's miserly uncle and meets a 'boy' working at the farm — the disguised Jeanette.
