2 Days in the Valley (1996)

In a sleepy bedroom community of LA's San Fernando Valley, the murder of a professional athlete by two hit men sets into motion a chain of events that puts the mundane lives of a dozen residents on a collision course. This clever tale tells the story of two hit men, a mistress, a nurse, a vindictive ex-wife, a wealthy art dealer and his lovelorn assistant, a suicidal writer and his dog, and a bitter cop and his partner.
