Fed up with the pile of miscellaneous debris his next door neighbor has stacked up along the property line, normally decent suburbanite Dan Ouellette decides to take matters into his own hands and arranges an accident while he and his wife are away for the weekend. But the simple plan goes horribly awry when an ensuing explosion causes unforeseen consequences. Wrought with guilt, but fearful of being discovered, Dan tries to live as normally as circumstances permit, as do his unfaithful wife, his increasingly distant son, and the devastated couple next door. Inevitably, though, as the cracks begin to widen, everyone involved is faced with personal consequences never previously imagined. But it is Dan alone who, as the police begin to close in, awakes each morning to the now-terrifying reality that life doesn't come with an Undo.
