“Debris” (NBC — series premiere, March 1)

When mysterious wreckage starts falling from the sky, a secretive international agency is tasked with figuring out what it is, where it came from, and most importantly, what it can do. British agent Finola Jones (Riann Steele) and American agent Bryan Beneventi (Jonathan Tucker) are partners who have very different styles. However, they have no choice but to trust each other. Every discovery is also a race against time, because shadowy outside forces want these powerful objects for their own nefarious purposes.
