About Doc Martin:

DOC MARTIN is a catchy comedy drama that stars Martin Clunes (Men Behaving Badly) as Martin Ellingham, whose truculence and tactless manner causes mayhem in a small Cornish community.

The series details the trials and tribulations of the brash Ellingham, once a celebrated London surgeon who left his job after developing a phobia to blood.

After retraining as a general practitioner, he gets a job in the beautiful but sleepy village of Portwenn, replacing their deceased local doctor-but his abrasive personality doesn't exactly mesh with the pace of life in Cornwall.
