A wicked tale of virility and large bank balances, self-made men and dolly birds . . .
Gunther Schmidt is celebrating his sixtieth birthday in style. "Happy Birthday, old boy! Welcome to the club!" cheer his sixty guests. But Gunther doesn't like this particular club - he doesn't like it at all. And while his loyal wife Marion has organised the lavish party personally and stood by him through good times and bad, she's no spring chicken herself and frankly it's bad for his image. Now the luscious Linda, currently on the arm of the mayor's son - now there's a visible demonstration of what really counts . . .
As Gunther embarks on the time-honored chase for a younger bit of skirt, little could he have suspected that the ladies might think differently - that Linda and Marion might have opinions of their own. And from the dog's home to the lingerie-party-from-hell, old wives and new girlfriends find they have more in common than one might expect. But as both sharpen their weapons in anticipation - the question remains: will the ladies who lunch really be able to take on the old boys network?
