After a month, Adrian meets Grace, mother of Tina, and fixes their marriage. But Tina disappears mysteriously and Dina was brought in to fill in her place.
Unaware of the knives they were holding against each other, Adrian and Dina get married. Their wild marriage life had just started when the shadow lurking around Adrian comes back to life with the help of Tina.
