Jurors in the John Travolta extortion trial have been played videos of the defendants planning the ￡18 million payout plot.
Paramedic Tarino Lightbourne - who treated Travolta's 16-year-old son Jett after the seizure which ultimately killed him in January - and his lawyer Pleasant Bridgewater are seen discussing their alleged demands with Travolta's attorney Michael McDermott in the secretly-taped footage.
McDermott - who was wearing a wire in co-operation with Bahamian police - is seen in a meeting with Lightbourne with Bridgewater on the phone.
McDermott said: "You know what were both doing here, OK?"
Lightbourne nodded and replied: "Yes."
McDermott added: "It's a criminal offence."
Lightbourne said: "Yes."
McDermott replied: "OK. If we get caught, we're both in trouble."
Lightbourne and Bridgewater both deny charges of attempting to extort and conspiring to extort by means of threats.
The footage is being used to show Lightbourne and Bridgewater tried to force Travolta to pay them to stop them releasing a document the actor had signed which said he didn't want Jett taken to a nearby hospital in the Bahamas for treatment.
