First of all, let my preface my suggestions by stating that I can’t read your mind – all the character and events teeming in your head about this story.? All I can read are the words you posted.

So first off: Taking your revised version literally — again, I can’t know what you mean to say, I can only know what you said — it seems to say that the foot and mouth disease ravaged people. (After all, it’s people who dwell in villages; livestock dwell in barns and in fields.) Well, humans can be afflicted with foot and mouth disease. But the symptoms and consequences are usually mild compared to the devastation the disease inflicts on livestock.? And it is the latter who are the victims of the disease in this story.

Second: from an outsider’s perspective — and everyone who reads your script will be an outsider — the character with the more interesting problem and struggle seems to be the Indian. Why? Because he’s an outsider; he has to clear an obstacle course of prejudice and distrust that the local woman, an insider, doesn’t.

Also, it usually better to frame a logline from the perspective of one primary character, AKA the protagonist, even when (as in this story) the protagonist must find and work with an ally.

So I suggest reframing the logline (and script) from the point of view of the Indian,

And you also want to signal to logline readers that this story is not fiction, that it’s based upon a real crisis. And I presume that crisis to be the English foot and mouth disease epidemic of 2001 that required the slaughter of over 6 million animals.? Not for food, but for burial — to contain the epidemic.

So, here’s my take:
When an epidemic of foot and mouth disease infects millions of English livestock in 2001, an Indian outsider forges an unlikely friendship with a local woman to save her farming community from economic ruin.
