C-137 Rick and Morty were supposed to be on the planet Arcturo for forty-five minutes. Unfortunately, a portal gun malfunction left them stranded. Rick's confident that he'll figure it out, but on a planet full of outdated technology, it looks like a short adventure is going to become a weekend trip. X-216 Rick is the complete opposite of C-137. He's anxious, withdrawn and paired with a Morty who's a little meaner than he is. But C-137 Morty gets attached to him--and his Rick has no choice but to deal with a broken portal gun, a Rick whose hands shake with anxiety and a Morty that likes to challenge everyone. Despite everything, C-137 doesn't lose his confidence. But what he doesn't know is that an enemy lurks on Arcturo. This enemy knows what frightens him, and as the week goes on, C-137 can only watch as his plans, relationships and sanity start to unravel. (Takes place after season five.)
