Lincoln's Light

Lincoln's ordinary life as a college student becomes complicated when she takes a job caring for an old invalid woman, five days a week from late afternoon until the following morning. The woman lives in a guesthouse behind a large mansion situated in a rural estate.
The woman requires little attention, so Lincoln has ample time to study and complete her class assignments. However, she starts to hear unusual sounds and sees light flashes in the middle of the night. She ignores them until one night she is physically attacked by an unseen force. The next morning, she convinces herself that she just imagined it all.
Disturbing dreams together with catastrophic environmental events happening worldwide makes her frightened and unsettled. She soon learns that the old woman has prior knowledge of everything. All this makes Lincoln question everything and everyone she ever believed in. Could it all be connected?
