When Kate's best friends sign her up for a holiday-themed dating service, she reluctantly joins, but has no idea just how much her life is about to change.

Kate's would-be date number one, Richard, tries to reconnect; Mac attempts to prove his independence, but learns he might need to ask for help.

Kate confronts past dating patterns after she matches with someone she ghosted; Mac and Evelyn roadtrip to Brighton; Callum holds a pop-up at the Pear Tree.

Kate's mother, Delilah, shows up for a holiday visit, throwing Mac and Kate for a loop; history repeating itself causes Callum and Kate to remember their past.

Kate has difficult decisions to make and turns to Delilah for help; despite Laura's commitment to not meddle, she wants to make things right for Callum and Kate.

As the twelfth date draws near, Kate is feeling confident in her choices; when new information comes to light, she can no longer deny her true feelings.
