Better Man is based on the true story of Van Tuong Nguyen, a 25-year-old Vietnamese-Australian man who was arrested in Singapore, convicted of drug trafficking and sentenced with the death penalty in 2005. The series follows the story of a young man who had a tough but loving upbringing with his twin brother and devoted mother. The story culminates in an extraordinary three-year legal battle to save the life of Nguyen, led by Julian McMahon, a Melbourne lawyer, and Lex Lasry QC, a Melbourne barrister.
