Four women -- Iris (Toni Collette), Paula (Lisa Kudrow), Margaret (Parker Posey) and Jane (Alanna Ubach) -- work as temps at Global Credit, a stoic, faceless megacorporation where their shared employment status creates a natural affinity among them. The quartet's sense of camaraderie crumbles, however, when another woman lands a choice assignment, things begin to vanish from the workplace, and mistrust and paranoia shred their relationship.
