Everybody loves a good wedding - and this adventure has it aisle.

Guests, including Petunia's Pa, are gathering for a celebration. Richard DaFodda and his intended are ready to be married and PROFESSOR HOWE and his trusty companion, Petunia, are ready to gatecrash it but things aren't going as planned.

A temporal anomaly, a number 29 bus and a soiled nappy are some of the hazards that have to be negotiated, as well as a jobsworth Traffic Warden.

Will the DaFodda wedding go without a hitch? Can time and destiny be put back on course? And will the Professor's saucer get a parking ticket?
