Two British academicians, a Christian girl and a Muslim Pakistani man fall in love with each other and decide to live together but an appalling incident changes their lives forever.

The logline doesn't make clear how and/or why their difference in religion is an issue or if it even is an issue. And an "appalling incident" is a very broad term that could be just about anything. Is the appalling incident connected to their religions or is it something random? It's not clear.
