Sky is still reeling from the fact that he is not the Red Ranger. He refuses to participate is group activities. After Jack and Bridge are given powered up bikes, Sky has just about had it. Meanwhile, Gruumm has hatched a plan to steal a truckload of diamonds to be converted to an energy source.
The Rangers are playing a game of light ball. But Sky insists that he doesn't have time for games. A giant robot, controlled by the criminal Ringbah, is attacking the city. Ringbah is attacking with his robot carelessly, when Gruumm orders him to get down to business. Jack rushes in to fight the robot. Sky insists that they form the Megazord. Mora orders Ringbah to retreat, because his energy is too low. Kat gives Jack and Bridge the Patrol Cycles, and Sky is jealous. Cruger receives a distress call from A Squad, but is unable to pinpoint their location. Gruumm sends the Krybots to steal diamonds to be converted into Hellarium Crystals. The Krybots attach a teleporter to the case of diamonds. The Rangers race to stop them. Jack and Sky must face an army of Krybots. While the other Rangers rush to protect the diamonds. Sydney uses her genetic power to use the power of the diamonds against the Krybots. Jack orders Sky to stay and watch the diamonds, while he and the others report to Cruger. Sydney begs to help protect the diamonds. Mora has a diamond that a Krybot stole used to power Ringbah's robot. Sydney is called in for backup, and Sky chooses to disobey orders and go as well. The Delta Runners destroy Ringbah's giant robot. The Blue Ranger judges Ringbah with the Judgement Scanner and he is found guilty. The Blue Ranger uses his Deltamax Striker to bring the criminal down. Ringbah is contained. With the Rangers gone, the Krybots are able to steal the rest of the diamonds.

- A picture of Sky's father is shown, he is seen wearing the Red Time Force Ranger costume.
- For a split second, when Sky puts the picture down, you can see it was replaced with a picture of the Himitsu Sentai Goranger. In-universe, the frame might have hi-tech features that switches images, the image of the Gorangers could be that of their possible Power Rangers equivalent, as it was implied past Power Rangers existed in Passing The Torch.
- The ending scene of the episode shows the first time that Jack and Sky start to get along, despite having small issues with each other in future episodes such as "Idol".
