"DOA" is a dandy film noir classic starring Edmond O'Brien. In this story, a guy is poisoned and only has a short time to live, so he spends what's left of his life looking to find the killer and bring them to justice. In many ways, "A Touch of Venom" is inspired by "DOA". In "A Touch of Venom", a terrorist group poisons Frank Cannon and he's only got 72 hours to live. His only hope is to do EXACTLY what they want and they promise then to give him the antidote.
So, what, exactly, do the terrorists want? One of their members (Sondra Locke) has run away and left them--and they demand Cannon find her and bring her to them. But why is she so important that they'd care? Well, apparently they're planning on blowing up a dam....and her knowledge of this might jeopardize their plan.
While this is a good episode, it lost a point or two simply because the idea was far from original. Still, it is worth seeing...especially id you haven't seen "DOA".
