When Professor Braintree disappears, his wife calls her Doctor for advice. Whilst giving Faith some counselling, an attempt is made on Keel's life - somebody thinks he is the Professor! Steed's plan to use Keel as bait brings the Doctor close to death on an operating-table, before the killer is unmasked and the Professor, unaware of all the fuss, returns home after suffering from temporary amnesia.
