As ITV1's hit comedy drama Doc Martin returns for a second series, ITV3 viewers are treated to an access-all-areas documentary, filmed on set in the Cornish fishing village of Port Isaac. The real-life village doubles as Portwenn, home to the truculent GP, played by the ever popular Martin Clunes. Caroline Catz continues in her role as school teacher Louisa Glasson and there are plenty of twists in store in their will-they-won't they relationship. (thetvdb.com)
