The Constant Factor
Constans (original)
A young man is confronted with corrupt and vindictive colleagues at work and negligent officials at the hospital where his mother is dying. As he searches quixotically for a steadfast moral code by which to live, he suffers from the knowledge of human frailty and our darker inclinations to do harm.
