wai tai hon (eric tsang) has been unemployed for a while, his wife left him with two children (daughter, miriam yeung, and son, yui tak shing) to raise and things are pretty tight. still, tai hon pretends to go to work, but spends his time sitting in a fast food restaurant with a group of other people, who all pretend they are at work. one day, tai hon's ex-boss (carol cheng arrives in the restaurant; she has been sacked, but she has a proposal - she want's to join the wai family, so that they can go on the 'frugal family' gameshow. eventually, he agrees...

so, the four enter the gameshow; they are moved into a new house in a tv studio and given hk$400 to last them a week, they will be competing against the lai family. the family with the most money at the end of the week will have all their debts paid off!

now, although i did quite enjoy this, it could have been so much better; it wasn't as funny as it should've been and it felt a bit rushed. miriam yeung was great though and i always like eric tsang.
