Picking up immediately where Anaconda 3 left off, herpetologist Amanda Hayes finally learns her employer Murdoch's true colors when he hires a doctor to harvest a fresh supply of blood orchids to experiment with the regenerative nectar on a baby snake in order to seek treatment for his own terminal illness. Amanda is forced to secretly bring together another team of scientists whom face off against a heavily armed squad of Murdoch's men to steal the coveted orchids before the killer Anaconda hunts both parties down.

Anacondas: Trail of Blood
11 May 2020 | by HorrorFan1984See all my reviews

After the baby snake from the killer Anaconda was salvaged from the fiery explosion in Anaconda 3, it grows at a rapid pace due to the blood orchid serum and is ready to attack.

We first see that the baby snake from the end of the third film is no longer a baby. The snake grew 5 times the normal size within days of the new serum being introduced into its system. The only downside is that it makes the creature far more aggressive than usual. The snake can now regenerate itself after a wound when the serum is given to it. It escapes capture and kills the Murdoch's scientist from the end of the 3rd movie. Murdoch hires a hitman to kill Amanda from the previous film because she knows too much. We also learn he has a week to live without the new serum so he wants results ASAP. Can Amanda survive Murdoch and the killer snake?

Anaconda 4 is another failure in the series, like the 3rd one. Both of which are made for television entires put out by SciFi TV. This one feels just as rushed and cheap as the third movie. We get very little character development which made me not feel for any of them when the snake attacks. Crystal Allen does a good job again, and Linden Ashby is a welcomed addition to the cast as well. Everyone else is in this movie just to be snake food.

I liked it slightly more than Anaconda 3, but that's not saying much.
