Ed begins by challenging the dads to navigate their way through the jungle to find their children, their journey includes a leap of faith from a 25ft cliff into deep water. One dad's overconfidence comes back to bite him while another realises just how much he is capable of if it means being reunited with his son. The teams then explore the depths of an ancient sinkhole, thought by Mayans to be the entrance to the underworld, with the fastest way to the bottom being a 160ft abseil.
