The Big Moment is an American television game show based on the original Japanese version called Happy Family Plan.
[1] It was originally an hour-long series, but due to low ratings, was cut to a half-hour after its second episode.
The show's premise centered on one member of a family (or group of people) who was given one week to practice a certain task before the episode's taping.
At the end of the week, the contestant (and his/her family and other supporters) came to the studio to perform the task.
The contestant was given only one attempt; if successful, he/she won a pre-selected prize package worth $25,000.
