It's about this plant/fungus that's growing out of a scientist and is killing/eating people. It turns out that the scientist has a son who is immune to whatever the plant is doing to people so they send him to the facility (army?) where the plant is growing from to kill it. Maybe it was suppose to be for biological warfare? (He also brings a woman along with him who he has to coat in his own blood so she won't get hurt) I believe he hasn't seen his father for years and years and it's really emotional for him...

I know it's vague but that's all I can remember. I think it's a slightly older film, maybe from the 80s or 90s? Any help would be really appreciative!

It may have been one of Sy Fy's "original movies" now that I think about it...so locating information on it might be near impossible.. ):
