Janssen makes a good woman-in-peril in this chiller. Marnie Watson was convicted of manslaughter for killing her abusive NYPD husband Mike (Pare) and must finish out her sentence under house arrest tethered to an ankle monitor. Her late husband's partner Shanks (Cannavale) still thinks the murder was deliberate and he's keeping a close eye on Marnie, hoping she screws up. Then Marnie starts getting abused again--from Mike's very vengeful ghost. She can't get away so Marnie has to get rid of Mike for good this time (which turns out to be the weakest part of the plot).
