Geoff Tippet has arranged a special birthday treat for his old friend, Bob. The treat is a hotel room for the night, a double-bed which folds up into the wall and an attractive girl called Mimi. Add a shy Kate who anxiously awaits her computer agency date - Dick, who has been shown into the wrong room; Bob's wife Liz, who believes she is dining with Geoff, and a connecting door between the two rooms and you have the recipe for a fast-moving and hilarious comedy.
