Clifton Falls part 3 will see the zombie virus spread inside the City hospital and on a Cargo Ship, as the robbers from Clifton Falls part 1 escape the UK.
Norman and Cheyanne are laying low on a Cargo Ship heading towards South America, but one of the robbers is dying after being attacked by the victim he murdered in the bank. He is put inside the engine room, hopefully to die in peace, but returns as an Undead creature to spread the virus. Meanwhile, the police officers of Clifton Falls have been called into the City hospital after a student is suddenly taken ill. No one knows what happened, but the student is sweating and burning up. Mike O'Sullivan wanted to hand in his notice after the horrific events in Clifton Falls, but now has to work out why the student has suddenly died.
