The Fugitive (1963)

S3E16 Not With a Whimper

Kimble arrives in the small industrial town of Hempstead Mills, West Virginia, to support his ailing mentor, Andrew McCallister, who is battling terminal lung cancer and is wheelchair-bound. Known for his passionate anti-smog efforts, McCallister is often dismissed as an eccentric. However, he has a dramatic farewell planned: a bomb hidden in a package that Kimble is to deliver to a local factory. When McCallister realizes that a group of schoolchildren will be touring the factory during the explosion, he urgently sends Kimble to evacuate the building and defuse the bomb before it's too late.
