Sex-Kliniken (2007)

Four college seniors open a bogus sex clinic, which unexpectedly mushrooms into a multi-million dollar business. Featuring a young Dennis Quaid in one of his earliest roles and Alan Reed (the original voice of Fred Flintstone) in his final film appearance.

Les Bingham takes umbrage that his ex-wife Katie has a new love in life. What he doesn't know is that her new paramour is lawyer Lou Springer. When Katie's sister Sally arrives and tells the two about her new, hip '70s marriage contract, Les and Katie decide to try to get together again under a more liberal marriage contract, like Katie's sister. But, unfortunately for the couple, the contract is planted with the seeds of self-destruction.
