Ant-Man,
trapped in his smallest size, returns home to find his lab wrecked and his wife
Jan—the Wasp—unconscious on the floor. The skylight above them begins to
shatter so Hank speedily opens an umbrella over Jan and jumps into a floor
vent. He hears Jan start to wake up but realizes he is trapped in the vent.
Jan’s chauffeur Charles enters the house to check on her and assures her he
will always be there to care for her, barely concealing his desire for her
money. His oily insinuating manner enrages Hank, listening from below the
floor. But Jan brushes him off, offended by the implications and Charles
departs, barely concealing a threat….
Hank calls
out to Jan but she can’t hear him so he throws together a slingshot from a
bobby pin and a rubber band and shoots his helmet where Jan can see it. She
looks in the vents and sees him. Relieved that he’s not dead, she shrinks and
joins him for a happy reunion….
Hank and
Jan get to work searching for an antidote to the chemical which trapped Hank at
ant size and soon, Hank believes he has isolated the relevant factor but they
are interrupted by the entrance of Whirlwind. The villain squirts Jan with
knockout gas, putting her out so he can carry her off but Hank hurriedly throws
the switches sealing the door and shutting off the lights. Whirlwind turns on a
flashlight and is surprised to see Hank, who was thought to be dead. Hank uses
an air hose to fire a projectile, breaking the villain’s flashlight. He strikes
a match and Hank turns on a gas jet, causing a minor explosion. After he
recovers, WW manages to turn on the lights to find Hank and Janet gone so he
leaves.…
Hank and
Jan are in hiding, Jan having shrunk to Wasp-size. Hank suggests that Whirlwind
and Charles may be working together as their greed sounds similar but Jan
rejects the notion. They continue to work on isolating the size-trap factor.
The stress of the project starts to divide them so to show her commitment to
Hank, Jan drinks the “trap factor,” causing her to suddenly grow into a giant
before returning to Wasp-size, leaving her stuck at that size. So they go back
to researching (with Hank still wondering why Whirlwind sounded like Charles) an
antidote with the added burden of having to rework all the lab equipment so
that it can be used by tiny people. There’s a knock at the door and Hank goes
to answer it with Orkie; they are blasted by an oxygen-destroying weapon and
Whirlwind enters, wielding a gun stolen from the Avengers. He fills the room
with oxygen-eating bubbles to force Wasp to return to her normal size. But Jan
dons one of Ant-Man’s helmets which has a beathing unit and avoids the baddie. Unable
to find her, Whirlwind contents himself with killing Ant-Man by setting fire to
the lab and departing. Wasp revives Hank and he turns on a water hose, creating
a stream though the flames and they jump in a box and travel across the room
where the stream ends. Hank begs Jan to fly out and save herself but she
reveals her wings are soaked and can’t fly. Hank and Jan struggle to fill a
balloon with helium and float toward the broken skylight but the balloon snags
on a sharp edge and bursts. The heroes manage to hang on to a fragment caught
on the glass and they climb up to the roof and out onto a tree branch. Jan
slips and Hank panics but she reveals there was nothing wrong with her wings
and she flies back to safety. Hank wants to wring her neck. They make their way
down the tree trunk and fall asleep at the base….
They awaken
the next morning to see the lab destroyed and the headline on the day’s
newspaper announced their deaths….
