6After a health scare, 77 year-old spinster Barbara goes to convalesce in the sleepy Somerset village of Winsleigh Green with her sister Pauline, who is now a widow. The sisters are like chalk and cheese - Barbara, outspoken and aloof and Pauline, good natured and homely - so it's not long before the tension starts to rise. But when Pauline accidentally knocks down a vagrant who goes by the name of Bisto Mulligan, the ladies find themselves with another houseguest. As he recovers, it becomes apparent that Bisto is not who he first seemed, and as the sisters get to know the kind and courageous man he really is, it's clear Bisto has the potential to change both of their lives. As the spring turns to summer, and Winsleigh Green comes to life, can the three friends make the changes they need to, to embrace fresh starts, new loves, new lives and new horizons. Or do old habits die too hard?
