Crushers: intergalactic Jacks-of-All-Trades who will take on any assignment for the right price. Crusher Joe heads a small team of these outer space troubleshooters that includes the cyborg Talos, the beautiful Alfin, and the obligatory kid sidekick Ricky. A routine assignment escorting a cryogenically frozen heiress to a medical facility goes awry when the girl goes missing and Joe and his team are left holding the bag.
