Against the grain – part I : run

There is an investigation for a murder in an abandoned warehouse in Oakland, California following a male versus female UFC retaliation fight. The winner of the fight, Kata Gonzalves, confesses to the murder of her biological father, Domenico de Santos, accidental by account of self-defense. Detective Zael Hernandez investigates the murder through accounts of the witnesses: Serafina Gonzalves, ex-wife and victim of Domenico's domestic abuse; and Linnaea Gonzalves, youngest daughter of Domenico and sister to Kata. While the oral history of the events is exposed, the truths are interwoven through the events Domenico and Kata lived that led up to the murder.
