Akhilan and Vimalan are the conjoined twins of genetic scientist Ramachandran, whose company makes Energion, a dietary supplement that promises to make geniuses out of children. When Russian journalist Volga tells them that there is something fishy about Energion and is mysteriously found dead, their lives are turned topsy-turvy.
Unfortunately the movie Maattrraan is not yet available on HBO Max.
