 The Hardys can't pass up this great opportunity for both adventure and mystery and get their gang together of Chet, Biff, and Tony, and head off for a camping trip to New Jersey.In the woods, they soon encounter a criminal gang of smugglers, combined with the “ghost” of the outlaw, and the New Jersey Devil himself, all attempting to thwart their mission.Following a one word clue of “fishhook”, the boys have their father's pilot, Jack Wayne, fly them over the pine barrens in their family plane, the Skyhappy Sal, so they may parachute into the wilderness.
