The Hunt for Howard Marks
Share
For 20 years, one man – Oxford-educated Dennis Howard Marks – was responsible for running an international drug market that shipped marijuana into the US by the ton. Frontline tells the story of the man who believed that he was too smart to be caught-and the DEA agent who was determined to prove him wrong.
