Vier sind einer zuviel (2013)

On her wedding day, Lisa discovers that her husband Felix is making her crossly unhappy - and vice versa. She moves out head over heels. While Felix quickly descends into homelessness, Lisa ends up in a shared flat with two men: Chris and Edgar. They are only friends with each other, so Lisa doesn't mind the visits from the ladies in the least. But then Lisa does have a thing with Chris - and is suddenly seduced by Edgar. Just as they are about to settle down with this ménage-à-trois, Felix is turned in to them by the police.
