Whirlybirds S01E09 - Diamond Smugglers

Chuck and P.T. are accused of smuggling diamonds into Mexico. A helicopter marked with their registration number, N975B, was seen there on the same day the diamonds were smuggled across the border. The pilots have an alibi and give the agents a client's address, confident the client will vouch that they had taken him on a fishing trip. Unfortunately, the address turns out to be a vacant lot! Now it's up to Chuck and P.T. to clear their name as they proceed to search for their missing "client".
