But all is overshadowed when a Canadian cult, the People of White, arrive to take over the island. The cultÕs demands soon shock the islanders. TimÕs ideological foe Graham Fytts sides with the cult, while Wilfred, JessicaÕs scheming small sisters Alice and Rosalind, and Darren Stocks with his beery friends all plot to evade its restrictions. The cultÕs members in return attempt to brainwash or convert the islanders. What might happen when the cult test Tim an JessicaÕs Christian beliefs? Can they still marry? Can the island be saved? Who might turn to violence? And where are those black birds?
