A family man and working stiff has a lucrative but illegal sideline in this comedy from Australia. Eddy (John Howard) makes his living as a fisherman in a small coastal town in New South Wales called Shellharbour -- or at least that's what his wife, Yvonne (Rebecca Frith), and his twentysomething daughter, Chantelle (Alyssa McClelland), think. Actually, Eddy and his partner, Dominic (Gyton Grantley), commit murders for hire when they aren't busy on the ocean. Eddy already has a slightly bumpy relationship with both Yvonne and Chantelle, but things become more complicated when Chantelle is given her walking papers by her Russian fiancé, and her new boyfriend turns out to be a ne'er-do-well who might be one of Eddy's upcoming targets. A Man's Gotta Do was written and directed by Chris Kennedy, who worked as a dentist before he found success as a filmmaker.
