Hard Rock Harrigan

YOU'VE SEEN HIM FACE DANGER BEFORE---but never like this!

Tim 'Hard Rock' Harrigan, a construction-crew driller working on the site of the Boulder Dam, is in a constant feud with his crew-boss 'Black Jack' Riley, because of Harrigan's dislike of Riley's hard-as-nails management of the men, and also because he and Riley are both courting the lady who bakes the pies at the camp commissary, 'Andy' Anderson.
