Fourth grade best friends, Betty, Wendy, and Sherri formed the Friendship League to help others and solve mysteries. Little did Betty know that their latest mystery would be at her own house during Passover!
This year, things are a little different when Wendy and Sherri join Betty's family for their traditional Passover Seder dinner. It's Sherri's first Seder and she's having fun learning what the holiday is all about, until something goes wrong, and the Friendship League ends up having a real mystery to solve. Everyone's a suspect, including Betty's mom, dad, grandparents, and annoying older brother...along with the Friendship League's number one trouble making friend, Barry. Even Betty's ever-hungry dog, Daisy, is under suspicion. Using a combination of logic and teamwork, the Friendship League is on the case!
