Broken Vessels(1999)

The story of two emergency medical technicians, Tom, an earnest and seemingly innocent young man from Pennsylvania who has moved to Los Angeles where he lands this intense and challenging job; and Jimmy, his unflappable and reliable veteran partner, who is seriously reckless and desperate. For both men, the thrill in "life-saving" is surpassed only by their thirst for a heroin-induced delirium. Their journey turns into an experiment into pushing the limits and it quickly evolves into a journey through the drug underworld as they careen off the edge and out of control.
