It’s the day before her daughter’s wedding and things are not going well for Gail Baines. First thing, she loses her job – or quits, depending who you ask. Then her ex-husband Max turns up at her door expecting to stay for the festivities. He doesn’t even have a suit. Instead, he’s brought memories, a shared sense of humour – and a cat looking for a new home.

Just as Gail is wondering what’s next, their daughter Debbie discovers her groom has been keeping a secret…
