Produced by hit-maker Ning Hao and directed by 34-year-old Wen Muye (Drug Dealer), who won the Golden Horse award for best new director with this film, it humorously and humanely describes the terrible reality of impoverished CML cancer patients unable to afford $70,000 a year worth of a life-saving meds.
The drug is Gleevec (called Glinic in the film), known as a miracle maintenance drug that allows some patients to reach a natural lifespan. It is patented by Swiss pharma giant Novartis (called Nuowa) but manufactured in India as a generic for a mere fraction of the cost. The film tells the true story of a small businessman who began smuggling the drug into China from India until he was apprehended by the police.
