Sukob is a 2006 Filipino horror film directed by Chito S. Roño and starring Kris Aquino and Claudine Barretto. Sukob was considered as the highest-grossing Filipino film of all-time earning ₱203 million, until 2009 when it was surpassed by the romance film You Changed My Life. The film's premise is based on a Filipino superstition sukob in which one should not get married within the same year an immediate relative dies or marries.
Overseas Filipino Worker Sandy (Kris Aquino) returns to the Philippines with Dale (Wendell Ramos) from Dubai, United Arab Emirates, for their wedding. Upon returning to her home, Sandy learns from a caretaker of her neighbor's house that Helen, Sandy's childhood friend, had died along with her family years ago. Her mother Tessie (Boots Anson-Roa) revealed that Helen announced her engagement after the recent death of her father Dr. Quisumbing despite being advised to postpone the wedding due to the old superstition that a marriage within the same year an immediate family member dies will be cursed. A few weeks after the wedding, Helen's husband perish in a plane crash while his wife dies in a bus accident at the crash site and Helen's mother suddenly disappears inside their home afterwards.
