I didn't see the remakes, but saw the original one with Jintara and Chatchai version. The story is mainly about Jintara's life, from childhood all the way to her marriage to p'ek (Chatchai) and then their 4 or 5 kids, don't quite remember how many kids she got... which all evolved the changing of times with the rulers(Kings), and I believe within her life period there were 4 Monarch changed. And when her husband pass away, her kids all grow up, causes problems and other family issues/drama etc.
