In the seaside town of Margate, Trish is pregnant and expecting a girl and her sisters Clare and Leila rally around her with their mum. But their other sister Mel makes an unexpected return and threatens to destabilise the entire family.

A flashback to Paris gives insight into Mel's life there and what went wrong. Back in the present day, Mel and Spencer have a difficult conversation. The next day, estate agent Trish is in her element selling a fancy house, but after picking up on Spencer's odd behaviour she later suspects that he is getting cold feet about buying their own dream home.
