Martina goes to the doctor for a persistent stomach ache, but the diagnosis is as unusual as it is disturbing: what's inside her aren't simple symptoms, but butterflies... or perhaps moths. Between confusion and disgust, Martina discovers that her body is hiding more than she can bear.

Alberto, a terminal patient, wakes up with the memories of Lazaro, a deceased young man whose brain was transplanted into his own. Alberto must deal with these foreign memories without interfering with the mourning of the people he is still fond of.
