The Beckett sisters – Ellen, Emma, Elizabeth and Evie – all need to shake things up.

Emma has been planning her dream wedding even since she was a little girl, and as soon as her boyfriend Blake finally proposes, she presumes that it can only be smooth sailing from then on.

Liz is a well respected and successful doctor and she expects her affair with a married colleague to turn into something more serious as soon as her partner can leave his wife. But that does seem to be taking a long time...

Evie and Craig are married with three children, but have lost their way. When Craig suggests a way to spice up their relationship, Evie is horrified – must she go through with Craig's plans in order to save her marriage?

And Ellen, the eldest sister and the anchor of the family, is dealing with a marriage breakdown and getting back into the dating game. But she wonders if she'll ever be able to let go and open her heart to love again.

There's never a perfect time for life-changing decisions – just the right time.
