Ever wish you could live your last week over again? Well, my name's Frank B. Parker and I get to all the time. I work for a secret government project experimenting in time travel. When things really get messed up, I'm the guinea pig they send back to fix everything. Catch is, I can only go back seven days.

Prologue: Day One

Conundrum: Frank Parker grins as he imagines the looks on his teams faces as he explains this situation.

"What's up Frank?"

"I need your help sir. I have to get inside the Navy Yard and save an NCIS agent."

Dr. Bradley Talmadge and the rest of the Backstep team can tell there by the tone in the chrononaut's voice that something unusual is going on. "Only problem is, he looks like my twin brother."

Tap, tap, tap. Frank B. Parker slowly turns around and looks into the green eyes of yet another NCIS agent.

"Gotta go sir."

Timothy McGee motions for Frank to follow him and the chrononaut sighs as he hangs up the phone. Tim leads him over to his car and hits the key fob asking,

"Who the hell are you and what the hell are you doing here?"

"You sure you want to know?" Frank says saucily.

"I just had lunch with someone who looks exactly like you. What is going on?"

Parker sighs as he wonders how to explain.

"I thought the Backstep program wasn't supposed to be implemented for a few more years." Tim hisses as he opens the car door and Frank stops in his tracks as he stares at the young man.

Finally Frank asks, "You...how do you know?"

Tim motions him inside the silver Porsche Boxter, "Come with me and stay down! If Gibbs sees you there will be Hell to pay!"
