Betty's mother turns up at the Spencer household unexpectedly, suitcase in hand, after leaving her husband and collapses on their couch. Betty feels that Dr Smedley should be contacted, and Frank is the one left to do it, but with the phone box out of action, he pays a visit to his new neighbour, Mr Faraday. Frank calls Dr Smedley but gives him Mr Faraday's address rather his own, and causes a misunderstanding. After all the confusion, Frank locks himself out of the house, and once again has to trouble Mr Faraday, this time for the use of his ladder. (thetvdb.com)
