Theres a film with Denzel, where he tries to get an transplant op for his son who is headed for death but Denzel doesnt have the right insurance for medical cover and cant get a better job for the money outright and so with things almost totally yet agonisingly out of his control, ends up loosing the plot and hi-jacks a hospital at gun-point and demands the treatment for his boy, with a few spanners in the works and the S.W.A.T team stalking his azz, in desperation he then has the idea of offering himself for the body part he's son needs.

Theres a moment i that film that is very, very sad.
