Christmas time is always a busy period for The Maintenance Team but this year, Bennie Barrier and his team embark on an experience like no other.
When Bruno Bus is sent into London to help support the London Buses, Chester Cone decides that it would be a great opportunity to visit his old workplaces. As Chester Cone, his nephew Costin Cone and Beatrice Barrier begin their exploration of London, Chester Cone is kidnapped and taken away to The Tower Of London.
When Beatrice Barrier contacts Bennie, the City Maintenance Team head to the Capital to track down Chester Cone whilst helping the London teams in some rather strange and wonderful adventures building up to Christmas Day. Can Bennie and his team save Chester Cone in time or will he become another memory in London's Recycling Plant?
