Martin has his second GMC assessment - mock surgery - and Buddy is missing. Meanwhile, Ken's arrival does not bring good news for Al and Bert, and Penhale is unhappy with the arrival of his predecessor, Mark Mylow (returning regular Stewart Wright), who tries to take charge of his investigation. Guest starring Conleth Hill (Game Of Thrones).

DOC MARTIN is a catchy comedy drama that stars Martin Clunes as the abrasive and tactless Dr. Martin Ellingham, a successful London surgeon who begins working as a General Practitioner in the seaside Cornish village of Portwenn after developing a problematic phobia of blood. Doc Martin soon finds he needs all the allies he can get as he tries to negotiate his way around village life with hilarious consequences.
