A pharmacy trunk is robbed and two men killed, the driver and his replacement, out for a trial run. The veteran driver, while showing him one of his shortcuts on the route, is held up by three guys. Four boxes of a some steroid-like muscle- building drug are taken. However, if the stuff is taken by a diabetic, it could be fatal. One guy is in a coma already. Goren and Eames must find the four boxes and get them off the street or wherever they went.
The police (our crew) finds these killers/thieves pretty fast and this case leads directly to one that's far worse: a pharmacist diluting cancer drugs and making a big profit (while hundreds of cancer victims dying because the medicine wasn't strong enough). Goren, Eames and the crew go after him, of course.
Unfortunately, the episode becomes another excuse for the typical Law & Order cultural agendas, such as having a reverend made to look greedy, having the corrupt pharmacist's excuse for committing his crime being that the man could keep his big financial pledge to his church, and a plug for euthanasia, et al..
