Based on a true story.
Crack smoking Mike Weiss is one half of Danziger & Weiss, the 'David' of a lawyer firm up against the 'Goliath' of US hospitals. These hospitals won't buy their clients' superior syringe, because they say their existing purchasing contracts prevent them from doing so. The fact that these syringes are loved by those hospital's nurses is just a detail.
The hospital doctors have signed a deal with the providers, paying them a commission on purchases they make from those providers.
Danziger & Weiss take on United Medical Health Supplies, the organization that represents the vendors, and their lawyers begin background checks on D&W, and their witness.
While D&W are hemorrhaging money, UMHO makes a generous contribution to a senator's re-election campaign, the only senator that's helping back their case. Needless to say, the senator withdraws her support for D&W's case. Meanwhile, the main source of D&W's regular legal work tells them they can't sub-contract any more legal work to them.
This is typical of a gripping case which has you locked in from the start. How it ends up affects everyone who ever gets an injection.
Serious stuff. This is a great film that, if it had a bigger cast would have been more successful, but no better.
