Struggle between a Liverpool Juvenile Liaison officer and a young and dangerous pyromaniac. 　　A tough detective reluctantly takes on the post of Juvenile Liaison Officer and becomes embroiled in the delinquency rife in an inner city area. 　　Violent Playground didn't get much American play in 1958, mainly because there was a glut of such films at the time. 　　The picture received a new lease on life in the early 1960s to cash in on the Man From UNCLE popularity of David McCallum.
