The Dekarangers encounter the Algolian Gas Drinkers following a high-speed pursuit, and while the Alienizer gang manages to retreat, Deka Break recovers a briefcase that they were carrying. Inside the briefcase is a top-secret virus called "Golden Snow", which was being experimented on the planet Leslie. As communications to Leslie have failed, Tetsu is assigned to travel to the planet to investigate while the other Dekarangers scout around for leads on the Gas Drinkers' whereabouts. Ban and Jasmine enter a nightclub, where Ban meets Marie Gold, a beautiful singer with the ability to temporarily stop time. She also reveals herself as an undercover SPD officer from Leslie. It is revealed that the Gas Drinkers released the Golden Snow virus on Leslie, turning the planet's population into machine slaves. Marie is the only survivor, as she was on patrol duty outside the planet. The gang's intention was to infect planets with the virus before selling the vaccine to them for a high price with the help of Agent Abrella; however, their plans were complicated by the Dekarangers' intervention upon their arrival on Earth.
