I enjoyed this plausible story more than many other flimsy flights of fantasy. The main character uses his wits and thinks on his feet, which leads to an enjoyable twist near the end.  I'm curious whether the actress who played Frankie was a last minute fill-in for a scheduled actor who was a no-show at taping.  Her acting was flat in comparison to the others, which made her easier to dislike as the antagonist.  Even her microphone was in odd contrast to the others.  Still, it was a good plot and the other actors' strong performances carried the day.
