Comedy set in an electrical superstore starring Richard Wilson and Mark Benton. Alan (Benton), assistant manager at 'Rocket' gets a chance to be the store manager on a busy bank holiday whilst his boss is away. However, it seems his boss has laid a trap for Alan in the shape of Frank (Wilson), a mid 60s guy on a trainee scheme. Alan is forced to oversee a man who knows nothing about electrical goods on the busiest day of the year. The staff of Rocket become ever convinced that Frank is in fact a spy sent from head office. This fuels Alan's ever-increasing paranoia that the bumbling berk is actually a skilled operator sent to assess Alan's management potential.
