This light western comedy finds the lovely widow Laura Breckenridge (Angie Dickenson) offering a $20,000 reward for the return of some gold her late husband had stolen from the Denver mint. She seduces the virginal Sam (Burt Reynolds) into leading a team to retrieve the gold, now lying at the bottom of the Platte River. With the help of local blacksmith Jedidiah Hooker (Ossie Davis) and the inventor O.W. Bandy (Clint Walker), the trio agrees to go for the gold in order to receive the reward and restore the good name to the Breckenridge family. Meanwhile, the villains (Rick Davis and Del Reeves) trail the heroes in hopes of grabbing the gold for themselves. The good guys must break into the mint to put back the money, but they need to fool the wary watchman and superintendent (William Shallert).
