The story of a single swallow who, taking a rest from southward flight at a mission in California, ultimately brings about the famed migration of swallows to the mission at San Juan Capistrano.

Migrating swallows are making their annual spring return to San Juan Capistrano, and a hungry cat awaits them.

This Traveltalk series short follows the route laid out by the famous chain of 21 Spanish missions, begun in 1769 and extending northward for over 500 miles, from San Diego to Sonoma, California. We stop briefly at San Luis Rey and San Juan Capistrano (to watch the swallows) as well as San Juan Bautista and other missions.
