Temperatures across the globe are dropping at an alarming rate, while the confused Rangers find themselves on an island. Lothor looks on gleefully as the Thunder Rangers battle the Wind Rangers until Blake and Hunter begin to come to their senses. A creature is sent down that is more formidable than ever; and the Rangers find that they have to get off the island before it sinks! Things take a turn for the worse when Hunter falls under a powerful spell that sends him on a murderous rampage for his brother, who is barely saved in time by the Wind Rangers.
