As the adults sit down to gossip over a long wedding lunch & the rest of the children rush off to play, a young boy slips out of sight beneath the table. At twelve years old, Tommy`s weak heart prevents him from joining his cousins` games, so he sets his MP3 player to record the voices chattering above him. But then the conversation turns to his mother`s death & he overhears something he was never meant to know: that she didn`t die of an illness, but suicide. Confused & hurt, Tommy keeps what he has learned to himself & begins his own secret investigation into what really happened. At the same time, his father & step-mother have problems of their own to contend with. Juan is racked by private grief & guilt after the death of one of his patients (a boy of his son`s age), & Alma, his second wife, senses an increasing distance in their marriage & gradually finds herself drawn back towards an old flame. As all three withdraw into their own worlds, leaving more & more unsaid between them, their family story moves inexorably, affectingly towards its devastating conclusion.
