Grace isn't exactly thrilled when her newly widowed mother, Jackie, asks to move in with her. They've never had a great relationship, and Grace likes her space--especially now that she's stuck at home during a pandemic. Then again, she needs help with the mortgage after losing her job. And maybe it'll be a chance for them to bond--or at least give each other a hand.
But living with Mother isn't for everyone. Good intentions turn bad soon after Jackie moves in. Old wounds fester; new ones open. Grace starts having nightmares about her disabled twin sister, who died when they were kids. And Jackie discovers that Grace secretly catfishes people online--a hobby Jackie thinks is unforgivable.
When Jackie makes an earth-shattering accusation against her, Grace sees it as an act of revenge, and it sends her spiraling into a sleep-deprived madness. As the walls close in, the ghosts of Grace's past collide with a new but familiar threat: Mom.
