David Garrett is our title character and he's a promising treating and research oncologist. He thinks he's found a way to cure the stuff although I can't vouch for scientific theories presented. What happens is that his first guinea pig pateint turns out to be the father played by Jeff Joslin who abandoned him and his mother and Garrett never knew him.
There's also a romantic angle with Garrett and Kendra Carelli. And there is a heart tugging performance from Matt Godson as a child cancer patient.
If you think you know what happens, you don't. There's a big old joker hidden in this plot. He's who makes you think.
