History is employed in quite a number of ways in Theerppu, from pushing a political point to eliciting a few laughs. Scriptwriter Murali Gopi and director Rathish Ambat had shown their interest in history, and the rewriting of it, in their previous venture Kammarasambhavam. Yet, as the film proceeds, one gets the gnawing feeling that all these historical references are aimed at covering up for all that is lacking in the script, which at its core, is a done-to-death revenge story.
In Theerppu too, there is much erasure and manufacturing of history by Ram Kumar (Vijay Babu), owner of a resort chain, who decks up his resorts with historical artefacts, most of which turn out to be fake. Mythili (Isha Talwar), his business partner and wife, is not exactly happy with his ways. Parameswaran Potty (Saiju Kurup), Ram's old friend, whose business is in doldrums, arrives at the resort with his wife to seek some investment to save their company. Some uncomfortable truths from the past come back to haunt Ram, with the arrival of Abdulla Marakkar (Prithviraj Sukumaran).
