This needs a lot more direction than it currently shows. Replace "Meena" with some description of what/who she is and the same for "Rahda" that says something more than she's a maid. Then replace "dwell" with something a *lot* more gripping.
There's a rich vein of possibilities in your subject matter, but this logline conjures the prospect of an interesting ten minutes (the "tragic event") followed by two hours of your protagonist sitting around "dwelling" on things. Even in drama, your protag needs to be active in some way - and I'm sure they are, but the logline doesn't yet express it. What you've described here is the first act of your plot, but you need to add the remaining 2/3 to properly lay out the potential of your screenplay.
"In the wake of tragedy, an Indian [???rich-woman?something deeper???] is forced to stand against the very roots of her society and [???plot???] through her relationship with her [???young?poor?ghost???] maid."
