Will Basil's trusty Angels prove he didn't steal a ruby before the police lock him away? Liam and Lucy replace original Angels in the places of India (who is on a slow-boat to China) and Molly (who has gone to get some milk).
Due to a computer program's 'Annual Job Review' stating that Liam is under performing as Basil's sidekick, Liam finds himself fired by Basil, and Anil is hired as the new sidekick and Liam is offered to run the Cafe so Anil and Liam swap places, but will this all turn out for the better or not?
Basil becomes a secret agent for the British Secret Service (Codename: Windbreaker) and along with the rest of the gang: Madison: Supergirl, Liam: Captain Green, Lucy: The Doll and Anil: Mighty Lion/Flaming Idiot by Basil, to spy on Cousin Mortimer, but who is the real villain?
Dave accidentally shrinks himself to the size of a microdot and is eaten by Anil. Basil shrinks himself and Liam down to rescue his old friend from the bubbling stomach acid.
During the filming of the gangs Robin Hood B-movie they decide to make, Bingo thinks it's all real. Can Basil stop his nephew Bingo from becoming a small, furry outlaw like it's 1973?
