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 though it's big on retro 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 fast approaching, Imogen and Anna devise a plan. Rather than sell up, they will train up, and make the parlour the newest destination on the South Coast foodie map.
