Doc Martin S05E03 - Born with a Shotgun

New receptionist Morwenna Newcross (Jessica Ransom) gets off to a bad start after arriving late on her first day, and her hyperactive behaviour leads Martin to believe she is high on drugs. Ruth tries to deal with an intruder on the farm who has stolen the hub caps from her car, and the sleepless nights begin to take their toll on Martin and Louisa, who are running out of ways to comfort their constantly wailing baby.
