Voir The Galaxy Railways, Season 1 - Episode 21

Headquarters receives a SDF distress signal from Planet Kowloon, a bizarre world known as the Deserted Planet of Labyrinths. Big One is dispatched, with Ivanov, from Intelligence, accompanying them. Upon their arrival, the crew finds Tille and Liffle, two botanical-humanoid beings that are scientists from another dimension. Ivanov does not trust them and coincidentally, Big One is attacked by a stalking alien vessel. Sirius Platoon's only means of escape is to head towards a dimensional rift, from which their enemy emerged. Bulge senses a trap, but with Big One taking heavy damage it's the only way.
