The Plot is a video game developed by Odin Computer Graphics and published by Firebird Software in 1988 for the Amstrad CPC and ZX Spectrum.
It is a parody of the Gunpowder Plot of 1605, with the player taking the role of Guy Fawkes in his attempt to blow up the English Houses of Parliament.
When enough sticks of dynamite have been collected, the special firework must be taken to the start screen and lit to complete the game.
This is a fairly straightforward but quite enjoyable platform and ladders game, a la Monty Mole.
It's programmed by Odin, and as you would expect, graphics and gameplay are highly polished... a tough challenge ... worthwhile buy for hardened platform freaks.
