Kathiruppor Pattiyal (2018)
Several Tamil films have dealt with the lives and struggles of cops who handle law and order, and traffic. Kathiruppor Pattiyal throws light on the cops who work in the RPF (Railway Protection Force). One such RPF officer, Williams (Aruldoss), is miffed with the fact that the public does not respect them when compared to cops who deal with law and order, or traffic. He decides to bring in strict rules and asks his subordinates not to show any mercy towards defaulters who mess with railway rules. With the help of his team, Williams nabs many passengers who violate rules in different ways, which include peeing on railway track, travelling without ticket, and so on.
