Champion athlete Frank Merrill stars in the tongue-in-cheek actioner Unknown Dangers. Merrill plays a theatrical reviewer who pans a stage melodrama, insisting that such things could never happen in real life. A group of theater managers decide to get their revenge by staging a phony kidnapping and luring the reviewer into the "crook's" lair. Merrill overhears these plans and allows himself to fall into the trap set for him, determined to have the last laugh. But as it turns out, he wanders into a den of genuine kidnappers who, of course, he assumes to be actors. Unaware of the real danger that he's in, Merrill makes short work of the crooks and rescues their female victim, leading to a zany Keystone-like climactic chase.
