《征服太阳》是一部家族争产剧，透着泰国豪门的恩怨与是非。得先看看这个故事的缘起：泰国Soriyatit财团百货公司的庆典上，继承人Rang See与为活动演出的Saeng Laa一见钟情，两人互许终生。时隔不久，Rang See迫于家族压力与并不相爱的Bparn Rawee结婚，婚后不久Rang See因车祸瘫痪，于是夫妻俩从孤儿院领养了Patgorn做为继承人。 Saeng Laa带着满腹的委屈到一个小镇生活，发现自己经怀有身孕，写信向Rang See求助不成，只能自己生下女儿Rang Rong独自养育，过着清苦压抑的生活，常常借酒浇愁。20年后，Saeng Laa因酒精中毒去世，临死前，她告诉了女儿的真实身份并嘱托Rang Rong为她报仇，夺回Soriyatit财团的继承权。带着母亲的遗愿，Rang Rong来到生父身边与Bparn Rawee和Patgorn展开了一场财产争夺大战......
