One night while waiting for a red light, Collin witnesses a white police officer gun down a black civilian. As Collin is haunted by the incident, he begins to have nightmares and experiences hallucinations. 
At the same time, Miles becomes distraught by the gentrification of Oakland, and a resulting sense of loss of identity, home, and belonging.  
Miles purchases a gun from a friend on the basis of self-protection, an action which Collin strongly disapproves. As Miles continues to display erratic behavior, Collin's ex-girlfriend Val warns Collin of the dangers that may come from a continued friendship with Miles. Later that evening while having dinner, Miles' gun accidentally ends up in the hands of his young son Sean, an incident which horrifies Sean's mother Ashley, forcing both Collin and Miles to leave the house. At a party, an agitated Miles assaults a black man who misinterpreted Miles' persona as cultural appropriation, leading to a fight between the two. Miles uses his gun to terrorize the party guests before being stopped by Collin. In an explosive argument, Collin criticizes Miles for his reckless behavior and the trouble it keeps causing him.
