Ayyan Mani works in the Institute of Theory and Research as a lowly personal assistant to a brilliant, insufferable astronomer, Arvind Acharya, who is obsessed with his theory about microscopic aliens falling to earth. Stranded in an ordinary life, Ayyan knows he may not be able to escape his realities. To entertain himself, and to cheer up his weary wife, he weaves an outrageous fiction around his ten-year-old son, setting in motion a chain of extraordinary events he is unable to stop. Meanwhile, a war is brewing between rival scientists at the Institute and a beautiful astrobiologist complicates matters further. An astute observer, Ayyan follows these events closely, inventing new ways to further his own cause. Serious Men is a brilliantly funny tale of science, love and hope.
