new timer for bath fan has green ground; not in box

I just moved in to a home built in the mid-1990s. Want to replace the bath fan switch to a timer. The new timer has a green ground wire. The old switch and box do not. The junction box is plastic. What to do with the green ground wire?

Note that the unit itself is a fan, light, and heater unit. The light switch is housed in the same junction box. Don't know if that makes a difference. I didn't have something like that in my old house.

Thanks for any advice. I'm sure this is very basic. I just couldn't find the answer in searching.

If the box is plastic..... there MUST be a ground in it. Look behind all the splices.

Thanks PJmax. I had not removed the light switch that was in the same box. Way in the back were two twisted bare copper wires, mostly white which I think was paint when installed. Most of the wires had this spray paint as well. I scratched off the paint and connected the green wire to this, and the rest of the connections were straightforward.
