Ever get the feeling you don't really belong in your family, that you're completely different to your relatives?
That's how 30-year-old interior decorator Harri Ryan has felt since she was a child despite being close to George, her twin brother, and loving parents Gloria and Duncan.
It's the second time Harri has tried to marry her fiancé James, and the second time she's had a panic attack, ended up in hospital in her wedding dress and the celebrations have to be called off.
Harri has lost the love of her life, but there's more to it than wedding nerves - and this time she wants the truth. George suspects there's something their parents aren't telling them. But in one week all will be revealed and their lives will change forever.
And Harri's not the only one suffering a crisis - George and his partner Aidan are struggling, her friend Susan thinks her marriage is dead and friend Melissa wants to kill her hubby. Something's got to give, but can they all come through this difficult time and find happiness?
No matter what you do, the truth will out.
