Crusher Joe: The OVA's - Season 1 Episode 1 The Ice Prison

It seems that a Crusher's work is never done. While taking some well-earned time off on a tropical vacation, Joe and his companions are called to duty by an urgent situation. An industrial accident in space has altered the trajectory of a frozen comet orbiting the planet Kabara, threatening to send it crashing into the planet's surface. To make matters worse, the comet is being used as a slave labor camp for political prisoners by a cruel dictator on the planet, Ghellstan. If the comet collides with Kabara, not only will it kill everyone on it, but it could cause massive damage to the planet itself. Joe and his crew are quickly dispatched to Kabara and tasked with altering the comet's trajectory away from the planet, averting the disaster and sending it harmlessly into space where the prisoners can be safely rescued.
