Plot:
New York City, a copter checks on an incoming ship. The crew has disappeared from the ship which is but into quarantine.

Think we're Haz-matted enough to clean any college dorm room...
As a number of cops and doctors examine the ship, they find that the lifebots haven't been used. During the search, they find the dead captain's body
and several of the crew who have exploded. The searchers reach the cargo hold and besides the cargo of coffee, a number of large green eggs are found.

Giant chest-bursting alien sacs are definitely the great way to enhance the flavor of coffee...
One of the eggs hatches and several of the cops and doctors explode. Lt. Aris was able to escape and run off...
Aris undergoes decontamination and is questioned by Colonel Stell Holmes about the ship, eggs, etc... The eggs that weren't hatched were deep
freezed. Let the bio-techno-babble about the "things" aren't eggs but bacterial sacs... Drain some of the liquid from the sac and inject into
the lab rat leads to another exploding. Colonel Holmes thinks the eggs would be planted in the sewers for explosives...
The group decides to check on the warehouse where the coffee is supposed to be delivered. The goons start a gunfight which leds to them getting
exploded by their eggs. Holmes quickly gets the warehouse quickly burnt down.
The scientists realize that the eggs are silicon-based not carbon-based. The eggs are from outer space. Colonel Holmes realizes that the Mars
mission where an astronaut, Hubbard, reported seeing a cavern of eggs that match the description of what she'd found. Unfortunately, Holmes sat on
the committee that found Hubbard not sane for the space program.
Holmes goes to talk with Hubbard. He isn't too happy with her but does get a bit more receptive after seeing some of the photos of the
eggs. He explains what he saw in the Martian cavern.

Who would mold a cavern entrance to like a Wamba mouth from Empire Strikes Back?

Maybe we should be careful around all these eggs it looks like Ridley Scott's Alien...
His partner, Hamiliton reported that Hubbard snapped under the pressure, etc...6 months later, Hamiliton died in a mysterious crash.
Holmes, Hubbard, and Aris decide to head down to South America to investigate the coffee plantation. Elsewhere, Hamiliton is on a boat
(faked his death) and plans to eliminate the investigative three.
Holmes gets trapped in her hotel bathroom with an egg. Hubbard thankfully is able to bust the door down and free her in time.
Hamiliton realizes from a distance that Stella Holmes escaped.
Hubbard flies by the plantation while Stella and Aris meet the coffee owners for a tour. Unfortunately, these 2 of the Investigative group
are quickly caught and tied up...
Hamiliton managed to sabotage the plane Hubbard was flying. Well, Hubbard did walk away from the crash. He spots the men picking the eggs
and knocks out one of the pickers and disguises himself.
Stella and Aris are taken to the egg room with Hamiliton who reveals he was taken over by the alien. However, Hubbard resisted the alien's
mind control. Hamiliton takes his captives to the Master, who grew from a seed brought back from Mars by Hamiliton. The eggs hatch from
heat. The Master starts to mind control Aris.
Hubbard who snuck into the factory with the pickers learns that Hamiliton is still alive and has Stella and Aris.
The Master eats Aris.

The Triffids are getting smaller and hungrier...
Stella gets an attempt at mind control and slowly shambles towards the carnivorous monster. Hubbard runs in and pulls her back and shoots at the
alien which catches fire. Hamiliton explodes.
The military run in to handle the goons. Hubbard and Stella ponder at the sky...Elsewhere, in a city in a pile of trash, an egg explodes cut
to credits.
