Geoff has arranged a special birthday treat for his old friend Bob whose marriage is on the rocks. The treat is a hotel room for the night, complete with champagne, a double bed and a very attractive girl called Mimi. Arriving at the hotel, Bob discovers Kate in his room and assumes she is Mimi. The shy Kate thinks Bob is her date from a computer dating agency. The confusion continues with the arrival of an amorous psychiatrist as well as Bob’s wife, who believes she is dining with Geoff. The whole mix-up is due to a highly excitable Italian waiter, who shows everybody to the wrong rooms and then makes matters worse by trying to correct his mistakes. An evening of delicious and uproarious fun, this comedy-farce has enjoyed tremendous success all over the world.
