|summary=Ravi's father-in-law, Norman, causes him no end of problems especially as he keeps being thrown out of care homes because of his bad behaviour. Therefore when Ravi's cousin Sonny comes up with an idea, it could be the answer to his problems and also appeal to many other elderly people who are fed up with the life facing pensioners in Britain. Can they, along with Norman, be persuaded to up sticks and move to a new home in a new continent?

When Ravi and his cousin Sonny decide to open the Best Exotic Marigold Hotel in Bangalore as a retirement home, they do not don't know whether they will get any takers. However, by advertising it as a newly restored palatial hotel that will provide a life of leisure, good weather and mango gin, they soon get a great deal of interest and are welcoming their new residents. Evelyn, Madge, Dorothy, Norman and all of the others who decide to move to the hotel have their own reasons for leaving Britain but they are all excited by the new opportunity and the lease of new life that it could provide.
It doesn't take long before the residents realise that things are not quite as they were advertised. The hotel is in a crumbling state, the staff are temperamental and the resident nurse seems to have more than a passing interest in feet. However, it does not take long before the hotel starts to feel like home and lifelong friendships are forged. Sadly though, most of the guests have their own worries and problems so luckily they start to form a support network which is more than they ever had with their families at home.
