Quadruplets with only two things in common: their birthday and parents. This dynamic foursome battle sibling rivalry at every turn, but when they're together, nothing can stop them.

Dawn has had enough of her brothers' gross out antics and finally gets her own room. It's a dream come true, until the quads realise they need each other more than they think.

The boys are taken with a new girl at school, but Dawn is sure she's up to something; when Tom's old ice dancing rival shows up, the kids vow the family will take him down.

The quadruplets try to impress Josie and the kids at school by watching an old horror movie and defying their parents. The terrified quads soon regret their decision.

The Quads are excited for the Halloween dance, but Dawn is afraid she will be asked to the dance; Ricky and Dicky are rivals over the same girl; Nicky thinks of the perfect costume.

Dicky and Dawn's constant battle for control of the remote nearly ruins Tom and Anne's anniversary, and the Quads' obsession with TV leads them to one-up each other.
