When they understand it won't be enough, one of them says "plz, Shenron, help us" and bim, Goku appears between them and joins forces in the Kamehameha.

Basically this movie is after bio Broly, and it was Goten, Trunks, and Videl that was searching for dragon balls. Gohan was training that time and when Broly showed up, Gohan ended up overwhelmed from Broly attacks. And the rest is what SyiS said.
