A scientist recruits volunteers for the trial of a new recreational drug
that exclusively affects women. Among them is "number 4," who becomes
emotionally involved with first the scientist, then his wife, a
well-known visual artist in the midst of a creative crisis. The
scientist is oblivious to the atrocities his new drug will bring to the
city; his wife is oblivious to the superfluousness of the objects she
committed her life to exhibiting in galleries and museums. Number 4's
presence pierces the couple's complacency, gradually undoing the many
certainties they've accumulated in their lives of ease.
