Ep 1. Old Dogs

In this episode of Doc Martin, titled "Old Dogs," the audience is reintroduced to the beloved grumpy doctor, Martin Ellingham. It has been months since Martin had proposed to Louisa last season, and the beginning of this episode shows him preparing for their wedding. However, Martin's excitement is short-lived when Louisa reveals that she is unsure if she wants to get married.

To add to Martin's troubles, a group of elderly patients begin experiencing bizarre symptoms that he cannot explain. Concerned for their health, Martin begins researching their symptoms to try to identify the cause of their illness.

Throughout the episode, Martin faces various challenges in both his personal and professional life. As he struggles to navigate his relationship with Louisa and care for his patients, it becomes increasingly clear that he may need to seek help from others to overcome these difficulties.

As always, the episode is filled with the same dry humor and eccentric characters that audiences have grown to love from the show. Martin's odd interactions with his patients and colleagues add a sense of lightheartedness to the otherwise serious themes explored in the episode.

Overall, "Old Dogs" offers a heartwarming and humorous continuation to the story of Doc Martin. It sets up a season filled with new challenges and discoveries for the beloved doctor.
