Charles Underhill (John McIntire) and his niece Anne (Suzanne Pleshette) offer a ride to Len (Robert Morse), the nice young man who helped Charles repair his stalled car. Shortly thereafter, Underhill learns that Len has spent several years in a reform school. Now in fear of his life, Underhill wonders how he can rid himself of the youthful hitchhiker -- but as it turns out, Len is the least of his worries. ~ Hal Erickson, Rovi
