Origins, titled Flight of Icarus, unveils a crucial part of Mike Franks' past, played by Kyle Schmid. Through flashbacks, viewers of the CBS crime series discovered new details about his family and his decision to join the Marine Corps during the Vietnam War era.

Showrunners Gina Lucita Monreal and David J. North discuss creating the backstory for Mike Franks on tonight's 'NCIS: Origins.'

Origins episode “Flight of Icarus” are ahead! Last month, NCIS: Origins spent its midseason finale wrapping up its Gibbs-centric flashback storyline, showing the final sequence of events that led to Austin Stowell’s character joining the Naval Investigative Service.

NCIS: Origins may be centered around Gibbs ( Austin Stowell) and telling the story of his life before what we saw on the mothership — the series begins on his first day at NIS — but it’s also telling us the backstory of another character franchise fans know well: Mike Franks ( Kyle Schmid ), then Gibbs’ boss.
