Where can I watch Half Heaven in United States?

Kizito, a self righteous, legalist preacher is mandated to take a one month soul winning trip to Mboko, a dreaded and godless ghetto, to validate his eligibility for ordination. He is rescued and aided by an infamous prostitute, Bisona who houses him for as long as he carries his assignment. This unlawful combination breeds a rare type of chemistry that eventually sparks to love. He later discovers Mboko means much more to him than just an assignment destination.
