Maggie Saunders is an almost sixty-year-old lesbian who's recovering from the loss of her partner. She lives on her family's farm next to a man-made lake. She interacts with natives and newcomers by boarding horses, storing boats, and running errands while she farms. Her closest friends comprise her reading group of a retired schoolteacher with land developer son, a grocery clerk who introduces her to noncommittal dating with disastrous results, a closeted lesbian brainiac retired from the CIA who asks Maggie for her first female kiss, and an LGBTQ/elder rights attorney who ultimately abandons her husband.

Maggie relies on a lifelong friendship with a local marina owner that's put to the ultimate test by a newcomer hiding that she's a displaced native suffering from severe depression brought on when her family was forced from their home to make way for a lake to generate electricity. Luxury homes surround the body of water that hides its secrets 150 feet below the surface.
