Sam enrols Juliet and the gang on a team-building course to improve their performance. However, the course leader has ulterior motives and Sam's plan backfires when Juliet is forced to quit her job.

It's spring-clean time at Babylon and Sam's main focus is on his team. He's enrolled them onto a team-building course to improve their performance, but Juliet isn't happy.

However, Sam is resolute and, as the gang attends the first set of exercises, the woman running the course identifies a serious problem in Juliet.

Meanwhile, Ben has befriended a homeless chap, Martin, who is masquerading as a hotel guest in order to have somewhere warm to sleep. Martin used to be a famous children's TV presenter but he's now fallen on hard times. Determined to rehabilitate him, Ben persuades Juliet to help. Wanting to prove her mettle to Sam, Juliet agrees and borrows a large sum of cash from Babylon to buy Martin a new suit and sends him for a job interview. But things go from bad to worse for Juliet when Martin seemingly disappears, along with valuables from the hotel.

Elsewhere, a large group of sci-fi geeks attend their yearly Captain Stranger convention, and Gino is bewitched by Mary, one of the attendees.
