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. Meanwhile, 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, and 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.
