The Firechasers (also known as Cause for Alarm) is a 1971 British crime film directed by Sidney Hayers and starring Chad Everett, Anjanette Comer, and Keith Barron.

While investigating the cause of a series of lethal fires in London, U.S. insurance man Quentin Barnaby falls in love with beautiful journalist Toby Collins.

Working alongside and pooling information with Toby and her photographer, Jim Maxwell, Barnaby hopes they share a common goal, that of "firechasing" the identity of the arsonist responsible.

The emphasis is on action and the photogenic qualities of the fires; but while these are mounted with due dramatic flair, the performances are generally wooden, though Keith Barron does manage to invest an unlikely role with some bite.
