Primarily, it is a voyage through memory, navigating through its inaccuracies and simultaneities. It unfolds with idealizations and disappointments, encapsulating its virtues and afflictions.

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.
