Two people [Emraan Hashmi, Soha Ali Khan] meet after a hiatus of six years. What starts off as a seemingly innocuous encounter on the same flight back to Mumbai, ends up as a rollercoaster ride through some of the darkest hours of Mumbai, as they see the city get swamped with disaster and loss... and are forced to stick together in this time of crisis. 26th July, 2005 remains etched in your memory and Im sure, every Mumbaikar wouldve a story to tell vis-à-vis what transpired with them or their beloved/relatives/friends/acquaintances on that fateful day. TUM MILE also highlights the dilemma of a couple, who once shared a beautiful relationship, but have moved on in life after they split, till they meet again on 26th July.
