Abbott Elementary takes a field trip to the Franklin Institute. Gregory is eager to spend time with a reluctant Janine who is avoiding him. Ava teaches the students about aliens, leading to chaos when someone spots an extraterrestrial in the museum.
A group of dedicated, passionate teachers and a slightly tone-deaf principal are brought together in a Philadelphia public school where, despite the odds stacked against them, they are determined to help their students succeed in life. Though these incredible public servants may be outnumbered and underfunded, they love what they do, even if they don't love the school district's less-than-stellar attitude toward educating children.
