The master of deception: how a fake illness hides a vigilante's true purpose
In short: A petty thief breaks into a house to exploit an elderly man with Alzheimer's. But the victim isn't losing his memory; he is using it as a weapon. In this complex thriller, the line between victim and predator blurs as a dark secret drives a man to hunt predators.
In the 2025 Tamil-language thriller Maareesan, directed by Sudheesh Sankar, the plot revolves around a deceptive game of cat and mouse. The story follows Dhayalan "Dhaya," a repeat offender, who attempts to exploit Velayudham Pillai "Velan" after discovering the old man has 25 lakh rupees in his bank account. To facilitate the theft, Dhaya attempts to gain Velan's trust, unaware that the elderly man is actually feigning Alzheimer's disease.
The mechanism behind Velan's deception is rooted in a tragic history. His wife, Meenakshi, was a child psychologist who gathered evidence against abusers, but her own Alzheimer's symptoms prevented her from testifying effectively in court. This failure led to the dismissal of her cases and her eventual suicide. Seeking retribution for his wife and the children she failed to protect, Velan used her journal of offenders to hunt and execute them, pretending to suffer from memory impairment to hide his tracks.
The film's narrative structure is a point of critical discussion. While some critics praised the exploration of morally flawed characters finding kinship, others noted a jarring tonal shift. For instance, Rajagopalan Venkataraman of Khaleej Times observed that the second half ditches the established tone, making the transition feel abrupt. Despite these stylistic shifts, the film explores how characters justify their crimes through different moral lenses, ultimately culminating in a violent confrontation between Dhaya, his partner Ganesh, and the vigilante Velan.
