On the third anniversary of a mass slaughter carried out by an apocalyptic religious sect called “Ark of Truth,” four people who lost loved ones in the sect travel to the scene of the tragedy. This pilgrimage takes them deep into the forest where the slaughter took place, and compels the travelers to reflect on the distant relationships with their deceased family members. Eventually, they encounter a former member of the sect and an unexpected turn of events provides the opportunity for resolution of past regrets.
