Spider plants are toughies..if there is still some green leaves there is hope..and as woofie said, if those roots still looks firm, it has a fighting chance.
See these photos: this one is a baby spider plant I have been callously taking care of during winter outdoors, I always end up stepping on it. So as the winter ensued, it did not do well..lots of dead leaves. I just placed it on top of one of my empty containers. As you can see, as dead looking as it is, the roots still look firm, and 2nd photo shows it is starting to produce a new leaf. During winter, my spider plants gets only the rain given by Mother Nature. As it is, our winter has been so dismal, but the spiders are ably surviving, those roots hoard enough moisture to see them through, and will resume active growing once temps are nicely warm again.
You can dip the roots in some water for a day or so, then move it to the usual soil media you have. Put it in part sun/part shade for now, in a warm area. Do not give it any fertilizer. Allow the plant to recover and acclimate again.
