"Charlotte returns to Sanditon with her fiancé in tow but is forced to come to terms with her unresolved feelings for Colbourne," reads the official synopsis.

"He, devastated, tries to move on and open his heart to another, but as they keep getting drawn together – can they keep on ignoring their feelings?

"Georgiana is horrified to discover a claim on her newfound inheritance. With the help of Samuel Colbourne, she battles in court to keep what is hers. The public attention and scrutiny sends her spiralling and she seems to be out of control.

"What she needs is a fiancé to send the circling fortune hunters away. What she gets is so much more.

"Edward, meanwhile, has promised Lady Denham he is truly reformed, but will Augusta Markham's fortune be too an irresistible a proposition?

"Lady Denham rediscovers an old flame from her youth, and together they back Tom's new plans for Sanditon – at the expense of his marriage with Mary (Kate Ashfield), and then she falls gravely ill...

"With weddings and failed engagements, will the Sanditon residents all find true love and happiness after all?"
