The "big hobby" of the title is photography, and the big hobbyist is an amateur cameraman (Kip King). This erstwhile shutterbug comes in handy during a manhunt conducted by police detectives Friday (Jack Webb) and Smith (Ben Alexander). The two cops are looking for a dangerous fugitive--and based on evidence gleaned from a detective magazine, the teenage cameraman thinks he's inadvertently snapped a picture of the man in question. ~ Hal Erickson, Rovi
