The Middleman (1975)

The unfortunate young man in this movie grew up in a moderately well-off Indian family which has now fallen on hard times. His ambitions for a career were dashed when his high grades were changed at the instigation of a vindictive professor at his school. Through a series of accidents, he finds a job as a factory-rep, or middleman. However, he does not prosper until he abandons his thoroughgoing rectitude and begins providing some extra services to people who can give him big accounts.
