Gibbs’ team solves a murder at sea in “NCIS” Season 14, episode 4. Don’t miss the episode on Tuesday, Oct. 11 at 8 p.m. EDT on CBS. CBS

CBS’ “NCIS” is going to solve another exciting murder case next week. This week, Gibbs and his team solved the case of a dead marine Sargent who fell from a roof. New team member Nick Torres successfully captured the killer before he tried to escape in Season 14, episode 3.

What will happen on the next episode of TV’s most watched drama? Well, Gibbs’ (Mark Harmon) team is going to investigate a tricky murder case. What makes the case in “NCIS” Season 14, episode 4 interesting is that it happens on a ship at sea.

According to the synopsis (via SpoilerTV), Gibbs, Alex Quinn (Jennifer Esposito) and Jimmy Palmer (Brian Dietzen) will travel out to sea and board a large ship, a destroyer, during a tiger cruise when the body of a Navy Lieutenant is found. Incidentally, the ship allowed civilians to stay as guests during the tiger cruise for one night. It is on this night that the Lieutenant was murdered.

Season 14, episode 4, titled “Love Boat,” will be a sensational case since the team doesn’t frequently investigate deaths on a ship at sea. It will also be interesting to see Quinn, Gibbs and Palmer work as a team in order to nab the killer.

The promo of the upcoming “NCIS” episode also reveals some spoilers. We learn that the murder investigation is somehow connected to a famous popstar. She was presumably on the ship during the cruise.

However, the murder investigation won’t be the only exciting aspect of the CBS series next week. Agent Timothy McGee (Sean Murray) will contemplate the perfect proposal for his long-time girlfriend Delilah Fielding (Margo Harshman). The trailer even shows him flaunting the exquisite diamond ring to his teammates.

Watch “NCIS” Season 14, episode 4 on Tuesday, Oct. 11 at 8 p.m. EDT on CBS.
