No Me Mandes a Mi (2012)

One Sunday morning, driving on an empty street, Sergio finds a briefcase on the floor, alone, without any I.D. and full of money. He thinks it's his lucky day. Three days later he finds an anonymous threatening note in his house asking for the money back and with specific instructions for the deliver. We discover that Sergio has been part of an specific plan to collect an amount of money for someone else.
