Ei8ht Shani (2006)

The London-based Rai family consists of Suraj, his wife Radha, their son and daughter, and Suraj's younger brother Raj. When Surah's son passes away, he gets very depressed, takes to alcohol, and gets intimate with Kamini, a young woman who ardently worships Lord Shani (Saturn)--and he promises to marry her. When he later decides that he loves Radha and their daughter Neetu more and wants to stay with them, he decides to break up with Kamini, who doesn't take it well--she kills herself. Suraj returns to his family and does not tell anyone about this incident. Then strange things start occurring in the household, which Suraj blames on Raj. This only worsens the situation, and the family, including Raj's voluptuous girlfriend Sapna, relocates to Balwant's house, where they find out that the vengeful spirit of Kamini has entrapped them, and they are all to suffer violent deaths, especially on dates that total to eight in combination with Saturday.
