The Life and Times of Juniper Lee
It Takes a Pillage
S1 E3:
When June's school chorus goes to a nursing home to perform, Roger finds half of a cursed Viking medallion. The entire chorus (including June's friends) are possessed by the spirits of Nordic Vikings. Her possessed friends then take to rampaging through the city to find the other half of the medallion, thus breaking the curse, and take up permanent residence in their bodies. June's hoping to nip that in the bud.
