Rebecca tells Dick the hospital needs a new computer costing two thousand pounds but he is otherwise occupied with inviting minor celebrities to Sir Geoffrey's birthday party in pursuit of that elusive knighthood, though Sir Geoffrey is dismayed that the guest list comprises mainly strangers. On the night Rebecca and her students kidnap Sir Geoffrey and demand the price of the computer as a ransom. Dick pays up, hoping to stop the cheque but finds Sir Geoffrey was in cahoots with the students all along and, thanks to them, is loving his party.
