Kappatoo (1990). S01 E04 = "TRACEY TIMES TWO" [Stars Denise van Outen as Tracey] [review]

"Kappatoo uses his wrist band to distort time at the football match so that everybody else is moving at a quarter of the speed of him, allowing him to score seventeen goals and his team win the match. Tracy, who Simon is madly in love with and who Kappatoo has been trying to impress for Simon as his part deal, agrees to come to the party with him that is being held at Simon’s house that night after Steve’s parents told Steve it could no longer be hosted at his house. She makes it clear though that, if she is left alone for more than ten seconds, she will leave. All is going well at the party until a pot gets broken and Kappatoo goes to investigate, leaving Tracy. She leaves annoyed and to stop the pot from getting broken, Kappatoo reverses time, as Tracy is outside of the space where time is rewound, another Tracy appears at the party. With some help from the computer and Steve, who coaxes Tracy back to the party, Kappatoo gets the two girls to touch and rewinds time, solving the issue. Simon's parents arrive not too happy with a party going on and a giant hole gushing water in the front garden after the washing machine blew a mains pipe after being used to make fuel for Kappatoo’s wrist band.

Simon watches the rest of the match and is overjoyed at how well Kappatoo has done, but his excitement is short-lived when Sigmasix beams into the dome and advises Simon that he is bringing a statutory declaration of charges against Kappatoo for cheating at The Hypergrid. Simon initially believes he can lie his way out of it, but the computer informs him he will have to wear a truth detector and to beat it would be impossible." - From Wikipedia.
