In Carry On Abroad (1972), Grainger played Miss Plunkett, an assistant to tour courier Stuart Farquhar (Kenneth Williams), a character type often played by Valerie Leon in earlier Carry On films. The couriers led a party that included Sid James, Joan Sims, Charles Hawtrey, Barbara Windsor, Kenneth Connor, June Whitfield, Sally Geeson, Carol Hawkins and Bernard Bresslaw on a weekend trip to the Spanish holiday resort of Elsbels. Her phlegmatic and slightly bemused approach to a series of disastrous situations culminated in her extricating the party from a foreign jail by making advances to the local police chief. In some ways this was a stereotypical Carry On part: a young woman in a uniform who, from time to time, was reduced to a state of semi-undress, as, for Example, when the touring party consumed an elixir with pronounced aphrodisiacal qualities.
