1x143 - Boruto: Naruto Next Generations

It is discovered that a wooden tag used to prevent unauthorized entry into the medical unit has been stolen, and the prison guards begin a search for the culprit. Until the offender is found, all prisoners are locked in their cells. Once the culprit is found, each of their cellmates will be forced into solitary confinement. If this happens and the team becomes separated from Kokuri, their mission could be jeopardized.
