Whats the bond between partners, between brothers, and between spouses? In L.A., Bill Holt handcuffs Sean Rickhart inside a rebar frame for a freeway pillar at a construction site; Bills going to bury Sean in quick-drying cement. Guided by the narration of Nin, Bills coke-snorting partner, we go back and forth over the past 48 hours to find out what brings Bill and Sean to this deadly scene. Missing money, cops on the take, Seans two brothers (one the leader of the mob, the other a camera-carrying simpleton), Bills wife, dead young police officers, infidelity, and Bill and Nins partnership make a mix as volatile and unstable as the cement is solid and immobile.
