A police chase ends with the officer being captured and held hostage by an escaped convict, Tom Arlen (James Olson). Near by at Five Mile Caverns, rangers are checking for rain water seeping into the caverns where tours are held. A cave in injures a workman and Gene Pearson (Dennis Cole) believes tours should be suspended, but Walt Clark (Lonny Chapman) reminds him that state senators are due to visit to inspect the caves. They decide to close the North Fork section of the caverns where the fall occurred.
As visitors assemble for a private tour, Senator Kate Lassiter (Susan Sullivan) arrives and is an old friend of Gene Pearson's. She wants to inspect all areas including the closed off North Fork. Gene takes the visitors on their tour. Kate meantime gets trapped following a second cave in at the North Fork entrance. She finds she is not alone as convict Tom Arlen has found his way into the caves. Gene hears Kate's cries for help and manages to rescue her and Tom, helping them to climb up the "chimney" to the 'Opera Hall' area where the people on the tour are waiting for him. A major rock fall in the 'Opera Hall' traps the tour party.
The story follows their trek to get out of the caves. Each character has flashbacks to the recent past. Professor Soames has problems relating to his daughter Anne (Sheila Larken) whilst Joe Johnson (Leslie Nielsen) has been suspended from the police force following the death of his partner Ray. Kate thinks back three years to when she and Gene were due to marry. Will there be a happy ending?
