I've started to watch The Border about a month ago, and as most Canadian series, this one grips you by the throat and doesn't let go.
This ep. was no exception. Not only the way they handled the new case was awesome (and again, showing how governments and intelligence agencies really "cares" about the little people), but the major story arc (Kessler, Darnell and the shooting) was beautifully (yet not fully ) resolved. And it was a treat to see Richard Chevellau again (he's a WONDERFUL actor).
This is what I like about The Border- everyone is on the edge, there's a lot at stake, and there's always some shady conspiracy and hidden agendas. Not to mention great character development. Don't miss this Canadian masterpiece =)
