The Forgotten Vow

The Preston family lost its heir eight years ago, when Elias went missing after a car accident, and there is a struggle for control going on inside the family. When the family traces him at last, a tycoon has him taken away from the village where he has been living. The wife left behind there is Nina. She had found him hurt, with no memory of who he was, and looked after him. They married and had two children. When the children were two, Elias fell into a coma, and Nina has cared for him through the six years since. She has been working in the Preston house to pay for his treatment, and nobody there knew whose wife she was. She learns at this point that Elias is the Preston heir. The family finds out that she is the woman who saved him and is about to accept her as his wife when another woman comes forward and says that she was the one who saved Elias. The woman is the daughter of someone who has turned against Nina and wants her in Nina's place. Nina is accused of lying and at one point is in danger of being kidnapped. The parentage of the two children is put to a DNA test. Elias is still in the coma while this goes on.
