Mrinal Sen's films Ekdin Pratidin, Kharij and Ekdin Achanak, considered amongst his best works, are sensitive portrayals of the middle-class psyche. Although not strictly forming a trilogy, having been produced years apart, each in its own way deals centrally with the idea of absence: the sudden absence of one member of a unit, exposing the absence of certain values, and leading to a qualitative change in relationships and attitudes amongst those left behind.
