Espinosa (Ricardo Darín) is an epileptic fortysomething who makes his living by stuffing creatures for the natural history museum in Buenos Aires. It is there that Espinosa meets friend and fellow taxidermist Sontag (Alejandro Awada). After picking up their paycheck at a nearby bank, Sontag kindly invites the lonely Espinosa to join him in the forests of southern Argentina for a brief hunting getaway. Soon after checking into their hotel, Sontag and Espinosa take to nature in hopes of bagging a buck, but their voyage takes a dark turn when, in the grip of another seizure, Espinosa accidentally shoots and kills hotel owner Dietrich (Manuel Rodal).
