Explores the numerous and remarkable ways that plants travel to disperse themselves in order to colonise new territory. Includes time-lapse shots of brambles, the shoots of which grow up to three inches a day. Seed dispersal by the wind is seen in such plants as the birdcage plant in the Californian desert and the dandelion in an English meadow. Water dispersal of seeds like the sea bean which might be carried by the sea for vast distances is also shown, but by far the most common method of dispersal is living courier. Examples shown are burdock seeds, grapple plants and devil's thorns that attach themselves to the coats and feet of animals, and trees and plants such as rowan, yew, cherry, plum, hawthorn and blackberry whose coloured fruits are eaten by birds that carry the seeds some distance from the parent plant.
