"The Wart"; alternate title A Story That Begins at the End) is a 2003 Indian body horror film directed by Murali Nair.
Krishnan Unni still lives in the past glory days and refuses to change with time.
The lesson here is if one doesn't change with time, the old customs and blind faith will become a burden and, if one persists, a time will come when they will take over, meaning all of a person's decisions will be based on how they traditionally did it or what the old scriptures or astrological charts dictate.
After a while, these old traditions and customs would be taken out as something personal to an individual or a group, associated with the god, and made into something holy.
Murali in the end shows how the wart which was growing in him escapes from Krishnan Unni and becomes a huge elephant.
