The play is set sometime in the future, where Jem has been alone on the spaceship Callisto 5 for 8 years. His only occupation is a variety of video games along with I.R.I.S’s voice, but her company is tedious. For instance, she is programmed to tell jokes but not to comprehend them. However, Jem’s main problem is the robot D.A.M.A.R.I.S who is programmed with a commercial babysitting programme suitable for a 9-year-old boy, and therefore not for Jem who is now 17 years old. Suddenly one day a fearsome space monster invades the spaceship and a fierce fight for life and death unfolds.
