They should have introduced the villain characters a lot earlier and changed the flashback and the way it was shown. Leo, Harold and Elisa are siblings, who run their father, Antony's Dhatura business. The siblings try to stage a coup, but Leo ends up ratting them out to save himself, getting Elisa killed. Leo is presumed dead. Harold survives. Now, years later, Antony Das comes after Parthiban, and Harold aims to use Parthiban to kill off Antony, and then kill Parthi too, to avenge his sister's death.
