Sea Patrol (2007)

S1E4 Irukandji

Mike finds himself in a difficult position, having to choose between rescuing a missing refugee girl and helping two of his shipmates who have been stung by the lethal irukandji jellyfish. As the Hammersley chases down pirates, the crew also comes to the aid of a family of undocumented immigrants trapped on a ship that’s barely seaworthy.
