“Killer Nurses” (** out of four) was a pretty conventional suspense melodrama about two traveling nurses (Mia Challis and Jonetta Kaiser) who begin investigating what’s going on at a local hospital when a fellow nurse dies under mysterious circumstances and other doctors and medical personnel (Rob Mayes, Mai Delapa, and others) seem to be trying to cover their tracks and cover things up. Certainly watchable with decent performances and production values but pretty by-the-numbers and could have used a shot of adrenaline. OK for what it is.
