Booth (David Boreanaz) and Brennan (Emily Deschanel) must work with the rest of their Jeffersonian team to save one of their own in the 20^th episode of "Bones" season 11.

In the episode titled "The Stiff in the Cliff," the couple will be assigned in a high-profile murder case involving a famous billionaire who was found dead in Antarctica. But when they found out the exact timeline when the billionaire was killed, they realized that one of their Jeffersonian colleagues could be included in the list of suspects.

According to the synopsis for the upcoming episode, "When the remains of famous billionaire explorer Henry Charles are found in Antarctica, the high profile case is brought to Brennan and Booth to determine if his death was a murder. The Jeffersonian team confirms he was killed when he went missing ten years ago on an expedition, but the timeframe puts the Jeffersonian's Dr. Clark Edison (guest star Eugene Levy), who was with Charles for the expedition, on the short list of suspects."

Can the team clear Dr. Edison's name from the crime?

Meanwhile, Cam's (Tamara Taylor) preparation for her wedding with Arastoo (Pej Vahdat) will hit a rough patch when her sister Felicia (Rochelle Aytes) comes to town. Felicia is expected to drop by to help with the wedding plans, but her appearance could further cause troubles for the bride-to-be.

Felicia will also try to persuade Cam to pick out the bridal and bridesmaid dresses that she likes. This will cause a big clash between the two. The differences in their choices will reportedly open up old wounds that could further keep them apart. Will the Saroyan sisters patch things up before Cam's upcoming wedding?

"Bones" season 11, episode 20 is scheduled to air on Thursday, June 23, on FOX.
