Kaliyoonjalu

Nandagopal (Mammootty), a high-ranking & rich IAS officer, pampers & raises his epileptic sister Ammu, resulting in her being short-tempered & spoilt. Nandan marries Gauri (Shobana) on condition that Gauri's younger brother Venu (Dileep) marries Ammu, without disclosing Ammu's condition. Although Venu learns of it, it was too late. After the marriage, Ammu finds it tough to adjust to Venu's environment, complicated by the fact that Nandan still catered to Ammu's whims & continued to pamper her. (Summary by iceblox)
