Text from back of the card:
The Ktarian Jol met Commander Riker on the planet Risa, where she seduced him and introduced him to a psychotropically addictive game. Riker shared the game with the Enterprise crew, putting them under Ktarian control. Jol was stopped when Wesley Crusher, visiting from Starfleet Academy, resisted playing the game and reactivated Data, who discovered a way to nullity the game's effects.
