Jack Neo's wildly popular Ah Boys To Men series continues next week (Feb 19) with Ah Boys To Men 3: Frogmen. This time, the endearing motley crew of National Service recruits must take on a whole new challenge - the gruelling training regimen of the Naval Diving Unit.

While the coming-of-age films have been described as melodramatic and unconvincing, Ah Boys To Men Parts 1 and 2 are still Singapore's highest-grossing local films of all time. Part 1, which came out in November 2012, made $6.2 million at the box office. Part 2, released in February the next year, eclipsed this by raking in $7.9 million.

In case you missed it, here is the boys' rite of passage so far (spoiler alert):

Spoilt brat Ken Chow (Joshua Tan) wants to dodge national service enlistment so that he can study abroad with his girlfriend. His mother (Irene Ang) sides with him, but his father (Richard Low) wants him to get into the elite Officer Cadet School.

When Ken arrives at Pulau Tekong, he is introduced to a host of characters - including the street-smart Lobang (Wang Wei Liang), the nerdy Aloysius Jin (Maxi Lim) and their tough-guy platoon sergeant (Tosh Zhang).

Ken is dumped by his girlfriend and promptly goes to desperate lengths to win her back and get off the island, including not drinking water and sleeping under a ceiling fan after dousing himself with cold water. He ends up in the hospital. To make things worse, his father has a stroke.

In Part 2, Ken decides to make good and to be the best recruit possible in Basic Military Training. This sets him up for a confrontation with the smooth-talking Lobang.

This time, Ken's buddy Man In Ping "IP Man" (Noah Yap) is dumped by his girlfriend for Zhen Zidan "Real Bullet" (Benjamin Mok). A lot of fighting ensues, some of it including faeces.

But all's well that ends well: the boys make it to their passing out parade, Ken's father is on the mend, and Lobang and Ken - who have patched up - are posted to Officer Cadet School.
