Cam Walker and his chums - aka the Outriders - are trying to raise the money to buy rock-climbing equipment. They're planning an expedition to the Pine Hollow woods to climb Eagle Tower, an ancient monument whose days are numbered. A mineral firm has been granted a licence to mine bauxite in the area and if the Outriders don't get there quickly, Eagle Tower will be no more. After a series of hair-raising adventures - including being rescued from a marina by enraged coastguards and chased off a golf course by gun-toting security guards - they finally get the money together.
