Prime Suspect on 'Lie to Me' (VIDEO)

What to do when the man responsible for lies starts lying? That's the question on the current 'Lie to Me' (Mon., 8PM ET on Fox).

[Spoiler alert.]

Dr. Cal Lightman (Tim Roth) enters the dangerous underground world of street-fighting on the latest episode. But then -- through a complete accident -- he is implicated in the murder of one of the fighters. Cal is the last person to be seen with the murder victim. That's not good. That's never the type of situation that you want to be in.

Now, in order to solve the crime, Cal must lie to the authorities. And he also has to involve his co-worker in a lie. What happens when the man who can solve all deceptions has to lie and then lie and then lyingly lie some more? ... Oh, sorry. Did we just blow your minds? Anyway, will Cal's plan work out or not?
