When Cornish veterinarian Mansley dies, his three estranged children reunite on the splendid coastal estate for his last will, ready to contest it (being hand-written) if his housekeeper, Heather Paddington, were to get a big share. In fact it assigns all to them provided they agree on turning it into a family home again. Second son Simon fell in love with Heather's niece Kathlin Grey before he recognized her, unaware she's jealous firstborn Patrick's fiancée, so neither dares betray him. While sister Jenny and her husband, attorney James Kenton, scheme, Simon discovers the truth about his parents.
