Jessie notices that Emma is constantly doing her homework at the last minute; now she is doing the same for her social studies report, which makes Jessie scold her just like her dad would do back at the military base. As she tries to take the children to the Battery Park, they get lost and have a wild subway adventure, with first taking the uptown train, then taking a downtown train to Chinatown and then the uptown train to Yorkville. Meanwhile, back at the penthouse, Luke starts break-dancing again, but he hears a scream coming from the kitchen. It turns out to be Bertram, who falls unconscious at the sight of a venomous spider called the speckled recluse (according to Bertram, the "deadliest spider on the planet"), so both of them try to get rid of it by using their "winging-it" ideas (mostly Luke's), leading them to their final plan. In the end, Emma finishes her homework using the experiences in the adventure while Luke and Bertram end up with hundreds of spider babies from the eggs that the speckled recluse laid.
