Roberto, a drummer in a rock band, keeps receiving weird phone calls and being followed by a mysterious man. One night he manages to catch up with his persecutor and tries to get him to talk but in the ensuing struggle he accidentally stabs him. He runs away, but he understands his troubles have just begun when the following day he receives an envelope with photos of him killing the man. Someone is killing all his friends and trying to frame him for the murders.

Medieval soldier of fortune Ettore is travelling through Europe with his partners looking for fight where they can earn some money. When they come across a Spanish castle under siege by the French army, Ettore first bides his time to determine which side is the winning one (and thus more likely to pay his fee). This is as first the French, but the treatment he receives from them is unpleasant enough to make him change his mind and turn to the Spanish side. Somehow, Ettore must rally the weakened Spanish troops to battle their enemy long enough for reinforcements to arrive.
