Robert Ayres plays a moody author with a suicide complex. Ayres' melancholia plays right into the hands of a gang of thieves. For a lofty fee, they convince the author to confess to their crimes and then kill himself. Yes, you're way ahead of us: Ayres has a change of heart and decides that he loves life. Delayed Action was produced by Robert Baker and Monty Berman, the men behind the popular 1960s TV adventure series The Saint.
