Merciless sorcerer El Kerim uses black magic and mind control to wrest power from the king. His next move is to steal Princess Jana, girlfriend to Capt. Sindbad . To stop El Kerim, Sindbad and his men must find and destroy a mythical tower that protects the sorcerer's heart. Along the way, Sindbad faces constant danger: a barrage of scimitar-wielding warriors, monstrous birds, a many-headed, fire-breathing dragon and even a massive, menacing fist.
