Tiara and her boyfriend goes on holiday with their friends to Bride's Waterfall. The legend states that anyone who prays under the waterfall will fall in love and live happily ever after. However, the waterfall also holds a frightening secret.

After experiencing a tragedy that took the life of her fiancé on Pulau Pengantin, Tiara decided to calm herself at a beach in Phuket, Thailand. She opened a small bar with her friend Lea and took the opportunity to study Thai Boxing as a way to channel her anger and trauma from the past. One day, her college friend Alan, who still had feelings for Tiara, came to visit and intended to persuade Tiara to return to Indonesia. Alan came with his niece Maureen, and nephews Kenny and Aida. As a good host, Lea quickly arranged their vacation, visiting the islands around Phuket. But when their boat broke down, they had to stop at a strange island. Tiara realized that something was odd on the island. She felt that her past would always chase her, wherever she went. This time, Tiara decided she would not run away. She would face it.
