Actress Toni Collette is set for a new ABC spy dramedy entitled "Unit Zero". The show will be produced by "Black-ish" producers, Kenya Barris and Lindsey Shockley. "Unit Zero" is about a CIA engineer who is a single mom. Collette plays the lead character who leads a team of CIA underlings when they are thrust into the field as first time spies. She and her inexperienced group spies are successfully, partly because no one expects them to be undercover spies. This will be a TV return for Collette. She was last seen in the 2013 CBS drama, 'Hostages' with co-star Dylan McDermott.
