Paranthe Wali Gali is an upcoming 2014 Indian romance comedy film directed and produced by the award winning playwright and theatre director Sachin Gupta under Chilsag-Civitech Motion Pictures.
The film tells the story of brilliant con man Irving Rosenfeld, who along with his equally cunning and seductive British partner Sydney Prosser is forced to work for a wild FBI agent Richie DiMaso.
