House by the Lake

A struggling couple, Scott and Karen, pack up their troubled young daughter and head to a picturesque lake house to reconnect and put their problems behind them. As Emma spends time with her new nanny, the little girl begins fixating on an imaginary friend she calls the Fish Man. Karen's fear of the strange man down the beach, Emma's fear of the water and her recurring sleepwalking continue to raise tensions in the house and drive a wedge between Scott and Karen until one night Emma disappears. When she's found breathing underwater in the tub, Emma insists she's been with the Fish Man. And he's coming back for her.
