This is a summary of an episode performed during Improvised Star Trek's initial live run at iO Chicago from October 17, 2009 through May 8, 2010. The adventures continue wherever you listen to podcasts.

Onboard the shuttlecraft SS The Rumpus, Cmdr Hayes and LtCmdr Watson are escorting their new Captain, Bill Spillman, to the USS Sisyphus. The two are excited by the new Captain's professionalism and eager to put their best foot forward, but the endeavor falls apart almost immediately upon arrival. Having heard of the new captain, Ambassador Tarsonis present himself and informs Spillman he boarded the ship six years ago but was never delivered to his destination. While the crew recognize Tarsonis from around the ship (he can occasionally be seen playing tennis) they had no idea that his presence is due to any mission. The situation leaves Cpt. Bill, who reviewed the ships logs before taking command, to delivers some bad news to the Ambassador. Since coming onboard the ship his planet, Tarsonis, has been destroyed, along with his people, the Tarsonis. Lt Cmdr Watson begins searching for a new home for Tarsonis, who has spent the last few years wandering the ship; occasionally seeking solitude in its abandoned, vermin-filled sections; or fruitlessly pleading his case to the ship's holographic visitor's guide, which he mistook for the previous Captain.

Meanwhile, Captain Bill's tour of the ship with Cmdr Hayes leaves him appalled. He concludes that by any metric: the ship's low rate of planet-saves; the rats and mice subsisting on Moriarty corpses in the holodeck; the rampant tagging from an ongoing turf war between the bridge crew and the arboretum staff; he's never been on a worse ship. He makes finding Tarsonis a new home the ship's primary mission, one which he'll observe closely to root out the ship's disfunction. One planet seems to show promise until its revealed the solar radiation is rapidly aging Tarsonis, another seems nice until he reveals he cannot breath, a third seems safe enough until it begins to turn the normally stoic ambassador into a maniacal villain. Running out of options they decide give Tarsonis a shuttlecraft, but he talks them into joining him to scout out one more planet. The shuttle is both mouse infested (not a long term-problem as Tarsonis can comfortably live off their waste), and tricked-out (having been previously claimed by a member of the arboretum gang). The latter helps the shuttle blend in on the first planet they encounter: an Earth colony where everyday is a Puerto Rico Day Parade. Tarsonis is content, and Captain Spillman admits the crew's success has earned them some shore leave. Fiesta!

With Special Guests Nathan Jansen as Captain Bill Spillman, Jim Fath as Ambassador Tarsonis, and Ted Tremper as Computer.
