Last Reach Point lighthouse on the beautiful Northlands coast has been home to the Jackson family for years. Now it's nearly toppling into the sea and Beth Jackson must find a new home for her ageing father, Bill, and her teenage son, Danny. A chance meeting with Gareth Dakers, the smooth local politician, leads to an unusual offer. He suggests Beth and her family move to his North London flat. Beth is reluctant to leave the rural idyll of Last Reach, but with little chance of finding either a job or a new home in Northlands, she knows she has no choice. The move to London is shock for all of the family, not least because the press have decided to follow the story of the Lighthouse Family, as they're now being called. Confronted with the traffic, the pollution and the crowds, Beth nearly turns straight round to head back, but she can't - she has nowhere to go. As Beth and her family square up the challenges their new life in the city offers, Beth begins to realise that there's more to Dakers' generous offer than meets the eye. It appears that city folk should never underestimate their country cousins...
