Something is lurking beneath the water's surface...

Recently widowed actress Casey Fletcher has escaped to her family's lake house for peace and quiet.

They look so perfect - just like Casey and her husband used to be.

But is anyone what they seem?

Casey has a detective sat at her kitchen table.

She has a man bound and gagged upstairs.

Casey will uncover dark truths so life-changing that nothing will ever be the same again.
