Agata loses her baby just after giving birth. Baptism cannot be done and the child's soul is destined for Limbo. However, Agata learns that in the northern mountains there seems to be a sanctuary where it is possible to resurrect children for a limited time but sufficient to baptize them. Agata sets out on a journey with her daughter's body hidden in a box. On the way she meets Lince, an enigmatic boy, who knows the places well and who offers her help, but asks for the contents of the box in exchange.
