Once again it appears that Roger Wilco has managed to survive the boarding of one of his ships and the subjucation of his crewmates unscathed. The Bjorn have taken over the Deepship 86, transforming its entire crew (sans Roger) into scoops of lemon sorbet. Roger must somehow rid the ship of the invading Bjorn and save his crewmates from their dessert-like fate in the process. Will he do it? Probably...after all, he's the hero!
