Dick, however, is worried that Sally's spot on prediction of the weather will attract unwanted attention and so, when she discovers that Rutherford is to be hit by tornados, he orders her to report otherwise.

Meanwhile, Sally tells Chaz, the Channel 10 anchorman, that she would like to start presenting the news instead, and so he agrees to let her interview Lightfoot in the company's box at the Rutherdome; but really, he intends to seduce her.

Meanwhile, Harry and Sally get a nasty surprise when throwing junk into the time space portal - a new alien (Mark McKinney).

Nina thinks Dick is an international terrorist; Judith is convinced he's a psychopathic serial killer itching to place Mary's head in a box.

Mary's first reaction is anger at being lied to again, but when pressed to think back with that added information, she flashes through disbelief, shock, surprise, brief nausea, then slow realisation and ending with finding it sexy to be dating a "spaceman".

Elsewhere, the local store has been robbed and Sally catches Don hiding in the frozen foods freezer, which he admits that he did because he was scared.

Harry takes a different line and asks the shopkeeper Sam out on a date, but later runs into her working at a posh restaurant, where she instructs him to call her Samantha.

At the end, as they sit out on the roof discussing the day's events, Harry receives a transmission from the Big Giant Head telling them that after a complaint from Liam about their changing him into an ape, their mission on earth has been terminated.

At home, Harry and Tommy are attempting to organize a farewell party for the aliens, but have no money, so they decide to max out their credit cards and not worry about paying the bill, since they'll be halfway across the galaxy - they even hire Elvis Costello to sing "Fly Me to the Moon".
