Choose Your Weapons
In many ways, this reminds me of another Bobby Vernon film, RENO OR BUST. That's because both films star Bobby and consist of him trying to rescue his lady from being forced to marry a man she doesn't love. However, in this case she's being forced to marry the king of a fictional country and the king, unbeknownst to his subjects, is already married.
