How much excitement can two ten year-old boys cram into a week's vacation and still be home safely for dinner every night? Dan and his seemingly dull country cousin, Willie Tucker, make a fair bid for honors in this division when they invade an army training grounds and help a raw, citified recruit get safely through maneuvers and back to his command post. Then, after Dan inadvertently gives the same soldier bad directions for sneaking back to camp from an evening of pub crawling, the boys are up at dawn to save him from drowning in a treacherous peat marsh. This is rural Wales where the highest virtue is knowing the terrain and Morgan doesn't aspire to any more substantial values. Still, she has a knack for bringing out the best in inarticulate, outwardly unpromising boys like Willie Tucker.
