Black Flies is the story of paramedic Ollie Cross and his first year on the job in mid-'90s New York. It is a ground's eye view of life on the streets: the shoot-outs, the bad cops, the unhinged medics, the hopeless patients, the dark humor in bizarre circumstances, and one medic's struggle to balance his desire to help against his own growing callousness. This story features lives that hang in the balance, including a single job with a misdiagnosed newborn that sends Cross and his partner into a life-changing struggle between good and evil.
