An unstable escaped convict terrorizes a woman who is alone with her two children.
 
This is not a bad suspense thriller and all the credit goes entirely to both Henson & Elba.  They play off each other great and keep your eyes locked on the screen from start to finish.  
 
FUN FACT:  The term malignant narcissist is used to describe Idris Elba's character by a member of the parole board, Idris uses the same term to describe a suspect in the first episode of the series Luther, in which he plays the lead character.
