Anaconda 4: Trail of Blood

The dying mogul, Murdoch, hires a doctor to harvest a fresh supply of blood orchids and experiment with the regenerative nectar on a baby snake. Overnight, the offspring grows monstrous enough in size and appetite to devour the good doctor whole, before slithering free on a regenerative rampage. The beautiful herpetologist, Amanda, dedicated to destroying the vicious beasts she helped create, leads a team of young scientists against a ruthless pack of Murdoch's armed thugs to get the coveted orchids before the snake hunts both factions down. The bloodthirsty offspring is seemingly invincible, sliding through explosions and gunfire only to regenerate and prey insatiably on anything in its path. (official distributor synopsis)
