At Saltwater Grange, Liv Harvey's ancient estate on the coast of Dorset, a group of lifelong friends gather in retirement, creating an upmarket commune for the hippy generation.

To outsiders like Liv's much-younger half-sister Justine, these dope-smoking pensioners with their organic garden and their talk of utopia look like an easy touch.

But Justine is wrong. Though long life has given them professional careers and respectable appearances, the Saltwater Eight have a dark past hidden behind the bohemian veneer.

Years later, they've paid their dues and reformed. They've even thrived in the system they wanted to destroy. But someone at the Grange thinks they haven't changed - and is intent on exacting revenge for events that happened a lifetime ago.
