Spider-Man frantically makes his way across town to
the train station, as Aunt May’s return train from her vacation is due any
moment! He passes a typically irate J. Jonah Jameson and reaches the train
station, ducking into the baggage room to change back to Peter Parker. Peter
meets up with Aunt May who is immediately concerned that Peter looks flushed.
Peter can’t tell her that he’s only overheated from swinging there top speed as
Spider-Man and so decides to play along. Nearby, two agents are transporting a
criminal called the Kangaroo, aiming to deport him, when suddenly he breaks
loose, using his leaping abilities to quickly escape out of reach.
The Kangaroo reminisces on how he got to this point.
He studied kangaroos back in Australia, quickly gaining their strength and
leaping abilities. When he tried to cash in on these talents as a boxer, he
nearly killed an opponent and was forced to flee the country, hitching a ride
to America as a stowaway. However, he was soon caught without a passport, and
was about to be deported, bringing us to the present. Meanwhile, Aunt May dotes
on Peter at her place, and he decides to go along with it despite not really
feeling sick if it brings her joy. Elsewhere, the Kangaroo aims to make some
quick cash by stealing an important case being transported by some guards.
Unbeknownst to him, the case contains a deadly, experimental bacteria that
could infect the whole city! The Kangaroo thinks the vial just contains jewels
and pockets it while he looks for another place to rob.
Back at Aunt May’s, Peter hears about the theft of the
bacteria on the TV and realizes he’ll need to slip away from Aunt May to go
into action as Spider-Man. Peter feigns being sick once more and sets up a web
dummy in the bed, hoping she won’t take too close a look. Spidey heads out
looking for the Kangaroo and eventually finds him attempting to rob a rooftop
party. Spidey swings down and tries to explain how deadly the vial really is,
but the Kangaroo refuses to listen. Spidey avoids the Kangaroo’s attacks while
afraid to fight back, lest he jostle the vial in the Kangaroo’s pocket too
much! Meanwhile, Aunt May goes to check on Peter and faints at the very sight
of the web dummy he set up!
Still unable to explain, Spidey is eventually able to
grab the Kangaroo and hold him upside down over the city. The vial falls from
his pocket and Spidey catches it with his web, making sure it’s fastened nice
and tight. The Kangaroo escapes while Spidey leaves the deadly vial for the
authorities. Spidey heads back to Aunt May and discovers her fainted over the
web dummy. He frantically checks to make sure she isn’t dead and changes back
to Peter. When she awakens, he convinces her that she was just seeing things,
while hating himself for making her think she’s going senile. Peter then
stresses about how much longer it’ll be until his double life as Spider-Man
destroys everything!
