Vivian, a documentary filmmaker believes the idea of marriage has grown old and outdated, and that a seven-year contract with a renewal option makes more sense. The three married couples she follows to illustrate her point couldn’t be more different…

For Alice and Noah, more than a hint of boredom is setting in as they approach their first decade together and the prospect of parenthood. Meanwhile, Alice’s funky sister Fanny is sure her “open marriage” to Zander is the key to their free-spirited happiness. And then there’s Cybil and Harvey, a pair of empty-nesters wondering what the next stage will be.

See the outstanding Dolly Wells as the manipulative Vivian, as she attempts to show how marriage is outmoded and the couples discover the “do’s” and “don’t’s” in their own relationships…

In Cinemas from 1st September.
