Amelia has a dream: toasting chestnuts by the fire with her husband Jack in their own cosy cottage. Their real life is another world - a cramped one-bedroom flat in Hackney. But when life takes a surprising turn, removal vans are soon heading to the Kent countryside. They soon realise the cottage makeover is a far bigger project than they'd anticipated. On top of that, there's Amelia's newly loved-up mum and her tearaway half-sister, Mirabel, to contend with - pushing Amelia and Jack's marriage to breaking point.
When Imogen and Anna unexpectedly inherit their grandmother Vivien's ice cream parlour, it turns both their lives upside-down. The Brighton shop is a seafront institution, but while it's big on charm it's critically low on customers. If the sisters don't turn things around quickly, their grandmother's legacy will disappear forever. With summer looming, Imogen and Anna devise a plan to return Vivien's to its former glory.
