The Chip Person.

Newly-sober, MARTY is attending AA meetings at the Road to Recovery Clubhouse. The clubhouse is run by CLEMENT, a "star" sponsor with a strong track record for keeping his sponsees sober. But Marty notices that, with disturbing regularity, the "weakest links" among Clement's sponsees keep flaming out spectacularly-- overdosing, committing suicide-- and Marty suspects that Clement is deliberately giving the most vulnerable a subtle kick and a shove over the edge. Clement is essentially a serial killer, but one that could never be arrested.
