What happens when the dead come back and can’t let go?

A catastrophe occurs in what was meant to be a fun-filled day for Nina and Alisha. Minutes ago, they were on the swings in the Rose Garden and now, Alisha is standing alone, while the help runs frantically. Her sister, Nina, has disappeared, never to be found again. But the bond between them withstands even death. Nina’s ghost circles the house. 

Is she here just to comfort her now lonely and distraught sister or is she pointing the way to unravel the mystery of her disappearance? the questions remain unanswered until six years later. 

Another ghost is reaching out to Alisha from the beyond, a ghost only she can see and she has no idea why. 
Battling the horror, the blood and the nightmares that follow her in this macabre turn of events, will Alisha be able to emerge from the whirlpool that the other side is trying to drown her in?
