The Commitment

S1, E4: Terry and Willie become involved with Brother Toby, a former drug addict now turned evangelist. They admire his mission to help other junkies become sober. He is framed by the father of one of his followers, because of the father's disagreement with Toby's religious beliefs. He is put in the situation where it appears that he violates his parole by selling drugs. Willie and Terry have the harrowing task of proving Toby innocent, in which they ultimately succeed.
