Jack ventures forth alone with his magic shoes, sword, cloak, and cap to rid the realm of troublesome giants. He encounters a giant terrorizing a knight and his lady. He cuts off the giant's legs then puts him to death. He discovers the giant's companion in a cave. Invisible in his cloak, Jack cuts off the giant's nose then slays him by plunging his sword into the monster's back. He frees the giant's captives and returns to the house of the knight and lady he earlier had rescued. A banquet is prepared, but it is interrupted by the two-headed giant Thunderdel chanting "Fee, fau, fum". Jack defeats and beheads the giant with a trick involving the house's moat and drawbridge.
