Chennai Express (2013)

Rahul, a middle-aged Mumbaikar man, embarks on a cross-country journey to Tamil Nadu to disperse his late grandfather's ashes in the Holy water of Rameshwaram. While travelling by train from Mumbai to Chennai, Rahul finds his life in grave danger when he encounters and falls for the cheerful daughter of a don mafia kingpin. After making a grave, costly mistake of helping four heavily armed to the teeth South Indian henchmen goons board the train, Rahul is left to fend for himself when the henchmen destroy his cell phone. As Rahul and Meena grow close whilst travelling across the spectacular South Indian lands of Chennai, an unanticipated and ominous looming danger awaits them.
