Night Train

It is a thriller film released direct to DVD in 2009 starring Danny Glover, Leelee Sobieski, and Steve Zahn.

 The story takes place on a train in which two passengers and the conductor find out that a man has passed away on the cabin. They discover that the man had a box with diamonds with him, and they keep it for themselves. Then, they dump his body in a river that the train passes by to make it look as if the guy never got on the train. The problem is that the box is supernatural, and whoever looks into it sees only what would temp them the most, dooming them to corruption and death before dawn. Because the body if found, police officers appear to investigate the death while different strange characters show up to get the box. Eventually, after a series of plot-twists, the conductor survives and tries to destroy the device by placing it in the path of an oncoming train. As he was severely injured, he dies just after seeing the boxed being moved away from the tracks by a little dog.

Kite.
