Moreen, a convent foundling, wants to uncover the truth of her parentage, so rather than marry, she takes to the road with a band of minstrels.
Colin, the fine minstrel bard, teases and taunts Moreen, trying to tempt her with his ribald verses and naughty tales. Colin helps Moreen become a singer who earns the minstrels' gold and keeps them out of trouble as they travel through castles and towns.
After she falls in love with Colin, he reveals why he's returning to Ireland: vengeance for his clan's defeat at the hands of Sir William Caddell, whom Colin plots to kill.
When they find that Moreen is Sir William's lost daughter, they're stunned. Can Colin kill his beloved's father; can she love Colin and be William's child?
