Speed

Plot:

Sam Hibbing is the largest dealer of speed on the West Coast, and has recently hijacked several million dollars worth of raw amphetamine powder, which he plans to auction in pill form to the highest bidder. The IMF substitutes Casey for Hibbing's rebellious, motorcycle-riding daughter, Margaret (who is herself hooked on speed). This allows Jim Phelps to insinuate himself close enough to Hibbing for Jim to intercept the speed when it is ready for shipment.
