Under pressure to write The Goon Show to end all Goon shows, Spike Milligan is planning his escape from a mental institution dressed in only his pyjamas.

After applying to the British Museum to get his marbles back, he starts to lose his grip on reality and threatens to kill all the Goons. Will his partners in Goon - Harry Secombe and Peter Sellers - be able to stop him?

Ying Tong is an hilarious and touching insight into the mind comic genius Spike Milligan who was an inspiration for comedians from Monty Python to The League of Gentlemen and loved by many including Eddie Izzard and Robin Williams.
