Doctor Who: Delta and the Bannermen (TV)

A Chimeron queen called Delta, the last surviving member of her race, is being pursued by the evil Gavrok and his Bannermen, intent on a mission of genocide. Delta finds herself on board a space bus of tourists en route to Earth when it is knocked off course by an American satellite and ends up at a Welsh holiday camp in 1959. The Doctor and Mel, having won a holiday with the tourists, help Delta to evade the rampaging Bannermen long enough to allow her child to hatch from its egg and grow to maturity.
