The two friends take on the craziest jobs and have built quite the reputation for themselves. When they find themselves on a small desert planet, stranded, their spaceship crashed, they don't lose hope. They've been through worse, right? But Tod's secret is revealed, and Phil suddenly disappears.
What is the desert planet's secret? Will the two couriers uncover the bigger picture before they're disintegrated by their invisible captor?
