This crazy series begins when Janet Wood and Chrissy Snow, two attractive women, have a going away party for their roommate, Eleanor (who we'll meet in Episode 44). While trying to find someone to share the rent with, they find party crasher Jack Tripper in their bathtub. They have their doubts at first but when they find out that Jack is the only one that can cook (by going to cooking school), they want him to stay. The hardest part of this is trying to convince the landlords, Stanley and Helen Roper, that Jack is indeed good company. Stanley doesn't like the idea of a man living with two women, knowing what can go on behind closed doors. Jack pretends he is gay so that he can have a place to live. It works, and the rest is sitcom history.

Jack is all set to move into Eleanor's room, until Chrissy's mother unexpectedly shows up. Chrissy's mom does not know that she and Janet live with a man, so she tries to keep them out of sight. Janet and Jack go to the Regal Beagle to hide out, and Mrs. Roper finds out that Jack is not really gay. She manages to keep it secret from Mr. Roper.
