You can view the official press release for the episode below;

Ben is stunned to discover that celebrity dentist, Jeremy Livingston, has dedicated his new book to him, especially because he hasn't got a clue who Jeremy is, as the comedy continues.

Meanwhile, Susan is stranded in an Albanian airport where a handsome stranger comes to her rescue when her bag is stolen. She is instantly smitten with The Doctor, a dashing American, who is heading off on an adventure around the world. The pair connect and he soon asks Susan to join him on his travels. But, could Susan really turn her back on Ben for a lifetime of romance, and could The Doctor really be all that he seems?

As Ben searches through some old memorabilia to jog his memory, he finally realises Jeremy was an old college mate whose work he always copied.

Jeremy invites Ben out for dinner to reminisce about the old days, but Ben's just in it for the free meal. It soon transpires Jeremy is actually jealous of Ben's mundane, fame-free life and is fed up with his celebrity lifestyle. Encouraged by Ben, and after a few too many drinks, Jeremy hastily dumps his book publisher, £1million dental floss contract and his glamorous, trophy wife.

The next day, Jeremy is feeling worse for wear and needs Ben to remind him of the previous night's events. He is horrified when Ben tells him what happened and leads Ben into a tricky situation that has disaster written all over it.

Ben is played by Robert Lindsay, Jeremy Livingston by David Haig, Susan by Zoë Wanamaker and The Doctor by John Barrowman.
