Growing up in the Mission district of San Francisco, Che Rivera (Benjamin Bratt) has always had to be tough to survive. He's a powerful man respected throughout the Mission barrio for his masculinity and his strength, as well as for his hobby building beautiful lowrider cars. A reformed inmate and recovering alcoholic, Che has worked hard to redeem his life and do right by his pride and joy: his only son, Jes, whom he has raised on his own after the death of his wife. Che's path to redemption is tested, however, when he discovers Jes is gay. To survive his neighborhood, Che has always lived with his fists. To survive as a complete man, he'll have to embrace a side of himself he's never shown.

A ferry filled with crewmen from the USS Nimitz and their families was blown up in New Orleans on Mardi Gras. BATF Doug Carlin is brought in to assist in the massive investigation, and gets attached to an experimental FBI surveillance unit, one that uses spacefolding technology to directly look back a little over four days into the past. While tracking down the bomber, Carlin gets an idea in his head: could they use the device to actually travel back in time and not only prevent the bombing but also the murder of a local woman whose truck was used in the bombing?
